Hi! I will look into it. Are there more details? Are you a new user? Do you have some tiles already? If you do, I’ll need those to reproduce the bug. What system are you running, Windows? You can try to clean your ui cache in User/AppData/Roaming/TilePipe2 - just delete the folder and the program should return to default examples folder on the next launch. If this does not help, then I guess something is wrong with one of the tile files, but the program should not crash either - that’s certainly a bug.
You would also help me greatly if you’d send the logs folder from User/AppData/Roaming/TilePipe2
