i added .tres files to 2nd archive, hope it will help :)
omg, thanks, sorry for taking so long to reply, i dont visit itch.io often, so i didnt saw the notifications.
tested here, the file : TilemapFiles/a_water_tileset.tres
is working fine.
the others have some issues (2 are empty and one the auto tile is not set)
but thanks anyway!
[edit] oh i see you didnt did auto tile for the others
