Thank you for all the details on the signs bug! It’s great to have many testers.
With so much information I was easily able to reproduce and fix it, so from 1.21 on, the signs text input should work properly without need to restart the game.
I also reproduced and fixed the bug with getting stuck on stairs. This one was more subtle and I am not 100% confident the fix covers all possibilities. I’m not able to reproduce it any more with the fix in, so I’ll assume it’s gone until proven otherwise.
But the bugs work has only taken less than 10% of my time over the past couple of days. The rest I spent working on a new game mechanic to do with new animals, which you haven’t seen yet. It’s about 50% ready, and will be the highlight feature of 1.21.
I’ll leave you to guess what it is for now, but it’s been requested many times and ticks all boxes on my list :-)
