As the weekend nears, more people have taken to testing the game and the result is more bugs discovered.
I made another adjustment to stairs placement. I am sure it’s still not ideal, but you can now do the below, although you need to start by placing all inside blocks and only then the outside (thanks to Alex Lesser for posting the problem screenshot):
Another bug is to do with wires sticking out of the wall after replacing gate with wire. I reproduced that and I’m working on a fix. The electricity format changed completely in 1.29, so this is only to be expected that there are little problems like that.
That means other platforms must stay patient for a little while longer.
