The issue isn't present when morphed, a random texture is picked instead

Alright, I can now empirically say that this issue is fixed.

Yeah, I already encountered this one. I'm hopefully gonna fix this in the next release.

So, I've now done the work so that this won't happen in the next release. The issue was that I was creating a entity that should be rendered every render (which is unperformant and memory-wise bad). This will be fixed in the new release (I've already pushed the fixed code to this repo).
