I created the map as usual, saved it, loaded it into the project, I launch it and it doesn’t work, I opened the map in notepad (.txt) and I see something like this: 3221225480 in one texture, and all the rest are normal, how can I fix this?

This number is a “global tile ID”, which apart from storing a number that can be traced back to a tile in one of the tilesets, also contains the flipped state of the tile. In binary form, it is `11000000000000000000000000001000`, so it has the highest two bits set, which means the tile was both horizontally and vertically flipped.

Please see [the documentation on global tile IDs](https://doc.mapeditor.org/en/stable/reference/global-tile-ids/#tile-flipping) for more information about reading these numbers.
