Hmm, the tile size shouldn't matter at all. Actually the "desert" example map that is set up with terrains as described in the documentation is also 32x32. Please ask for help on the Tiled forum or open an issue on GitHub, and provide screenshots which may help to understand what's going wrong. Thanks!
I think it was my fault, just the map was not of correct kind I guess. When you go in tiled and make new tileset and when you click on palette called tilesets - the program crashes. I detached it and it is floating window now but when you click in it, the program crashes. Anyone had same problem? I haven't made new map yet, only defined the tileset for it.
