Newest one, happened around level 35-ish. I did forget to get a screenshot this time- and I'm not sure about the first but these last two were teleporting heavy with terraformer, so that may be something
So, we'll see. Just pushed an update fixing both errors (just missing null checks) that were found in your log file. Not exactly sure if they are the cause but pretty likely. One was on polymorphing so probably just a vampire transforming to bat or back. Other bug seemed to be for destroying all tiles of specific color.
On the other hand, I also fixed (at least a bit) the mobile on screen keyboard on the web build so it's not way too tiny. Still far from perfect or optimal experience overall on mobile but just tried to make it somewhat playable. 😅
