[NOTE] Stale tilesets cause issues with importer #302
Description
I don't really consider this a bug personally as I don't think the importer is to blame, but I wanted to make a note of it here since I didn't notice the problem until trying to import with Unity.
I was getting the import error on my map of "Could not find tile ##" which I've seen other related issues, but none seemed to fix my issue (Max Sprite size in Unity, PPU, etc). My specific problem was caused by a "stale" tileset in Tiled that hadn't had its metadata in the TSX file udpated properly. I didn't have said tileset opened in Tiled, but had made changes to the root sheet in Aseprite, adding more tiles and increasing the base image size. Because of this, Tiled hadn't updated the data in the tsx file to properly reflect how many tiles were in the sheet. As a result, Tiled was (somehow?) handling this tilesheet properly and letting me add all the tiles from the set, but the importer was failing to find the tile references.
Re-opening the tilesheet in Tiled caused it to update the metadata on the tsx file and thus, fixed the importer!
As mentioned, I don't really think this is a bug, but since I didn't find anything mentioning this problem expressly I wanted to make a post here for future reference!
