Post the code related to these lines would be more usefull if someone try to help you.

Solved.

The same bug occurred afterwards, and gdb managed to get the tile where the bug was occurring. I believe it was caused by a change in items.otb. Spawns that had part of them "in the air", such as a spawn on top of a small bridge, caused it to be a tile in the game, but at the same time it did not exist, which caused a null tile in the function.
