Crash when painting in Manual tilemap mode with no existing tiles

I’m using Aseprite v1.3.17 on Windows (Steam version).

When I create a new tilemap, switch to Manual mode, and try to paint on the canvas with a brush while no tiles exist yet, Aseprite crashes immediately.

This issue does not occur if I first create at least one tile using Auto or Stack mode. However, if I undo all tile creations and return to Manual mode, attempting to paint again causes the program to freeze or stop responding.

Please let me know if you need any additional information. I’d be happy to help reproduce or provide more details.

Hi @Era_Soren, there is a fix for this to be released in the next version:
