I’m still having crashing issues, but I really think it’s unrelated to the paper 2d tile map update.
Basically, when I wasn’t sure the tile map issue would ever be fixed I moved on and removed it from my project. I then updated that project without the tile map component to 4.12. I had crashes after the update related to the update. I fixe those crashes.
When you posted this fix, I went back to the old 4.11 project with the tile map component. I had to update that project to 4.12. And as a result I got the crashes I originally had that were unrelated to the tile map. I’m not 100% sure how I fixed them anymore. So I’m still having those crashes. One time, though, the project happened to load without crashing, and the collision mesh got generated properly with the new tile map code.
I’ll create a new project in a bit to double check that collision tile map does indeed work.
