1.21.1 Is Coming

I’ve been monitoring your comments, emails and the forum after publishing 1.21.0. It’s great to have so many testers, thank you!

So far, I can see you found two serious issues with 1.21.0:

  1. Random freezes reported on multiple devices
  2. The fences bug is still there

#2, the fences bug. It’s really silly on my part. If you remember my old post, while working on coal blocks some time ago I found a lot of issues with terrain updates. These were causing random blocks disappearances, coal blocks would get put out, black lines would appear across the landscape, and (as I thought) the fences problem. Back then, I have drilled to the bottom of it and fixed the underlying cause. I was so happy about it (it was big) that I only tested it on coal blocks and ticked it off as done!

Now, after you told me 1.21 still has the fences issue, I had a second look and I found that, actually, the fences problem was caused by something else. Fortunately much more benign :-) It’s a single-line change to fix it. The issue must have been present since the fences were added, back in time immemorial.

One niggle is you will have to rebuild the glitched sections of fences – i.e. they will not get fixed automatically. But once you do it, they should no longer break. Alternative way to fix it is to place or remove a block next to the glitched fence. That should fix it as well.

Now for the #1, freezing bug. This is one of these nightmarish ones that will make me wake up in the middle of the night sweating. And get a lot of gray hairs. I can’t see anything that could cause it, neither have I come across it while testing on my 10+ different Android devices. It looks very much like the hardware-related random crash/freeze that used to occur on Nexus 10 only, but now extended to all devices. In short, a terrifying prospect! I have one backup plan – roll back one of the libraries I use to the previous version (as used in 1.20) and see if that helps.

I also found several small issues: wires sticking inside of lightbulbs, too frequent footstep sounds when walking and incomplete whistle description in Recipaedia.

I am now going to release 1.21.1, which contains all the above changes. Please keep testing!

      i noticed actually they do not disappear, they detach from the block?


      this happend when i reload world

    • Posted April 18, 2013 at 03:55 | Permalink | Reply

      The disappearing lamps issue was most likely due to the massive terrain update bug – all fixed in 1.21.

        not fixed, its still happen i tested this while ago. Replaced the lightbulbs, I flew a little around my world , restart level and lamps are gone… i have 1.21 :(
        but this happen only with those 2 lamps on my entire world

        i sent u my world so u can look at this yourself.

        i have this bug from begining since i bought the game(the version that you added electricity).

          SORRY Kaalus.
          I replaced the entire block with lamps not lamp only and after several test its look like it doesnt disappear anymore! :)

          ok UNFORTUNATELY I was wrong. Lightbulbs still detach the block but only when they are powered!

        • Posted April 18, 2013 at 04:57 | Permalink

          Thanks for the world. I can’t get the lamps to disappear yet, but using your map I found another problem with electricity that might be indirectly causing it and it’s 100% reproducible. So already something to do for 1.21.2. The problem is in the very bowels of the electricity code, I’ll look at it tomorrow. Time to go to sleep…

    My Samsung galaxy tab 2 7.0 is having both the fence bug and the freezing bug, oh and sometimes when I go far away for a long Time, my animals (horses, camels and giraffes) disappear :-[

      Maybe the animals were secret spies.And went on a mission when you left.. It might be A bug….I’m just using my imagination… -_-

      1.21.1 is out, please download and check whether it freezes as well. It would be very useful if you could tell me where in the game is it freezing most often. Even better, if you could get a repeatable freeze (i.e. you know what to do to make it freeze 100% of the time).

      Hi Olivia,

      Thank you, I hope you read my posts and understand why Google Play folks get it first. To get the game on the Kindle requires going through a lengthy certification process. Once I publish it there, I can’t change anything until it’s approved or rejected. With Google Play, I have full freedom of publishing at any time, and everyone can download it within hours.

      Don’t worry, Kindle will get it as well, and probably soon. 1.21 definitely works fine on my test Kindle Fire :-)

        • Posted April 18, 2013 at 04:09 | Permalink

          Roughly the same time as the Kindle. We had two certification races between Microsoft and Amazon so far. It’s 1:1 (Amazon won once and Microsoft once).

        Thank you kaalus.You just made my day.I will be patient…And when I get the update.IL TELL U RIGHT AWAY!! I will do anything for you and Survivalcraft.

    I really like the new update. Its quite a blast riding on a horse in creative. I have noticed something else, however. The first time I put my saddle on a horse and killed the horse (I found one the color I actually wanted), I got the saddle back. The second time, I didn’t. Was this meant to be? I don’t really know. So I’ll leave that to the rest of the commenting community… :)

    The frezzing part that I in counter was just it took about min and sum seconds to open the new 1.21 up but after that everything was fine :-) . Though the stares still makes the survival man jerk when stepping up to many in a roll.
