Not so functional tileset

[skinkcode]

Describe the bug

(Important one, I guess)
The Tile sets in Deltarune don't load properlly, most of them are shown as chess tiles (which shouldn't be happening)

(Less important one, I guess)
When I try to load tile sets in AntonBlast, they are all messed

Note: I'm pretty much sure nobody has reported this bug yet, but if someone did, then sorry for the disturb)

Reproducing steps

1-Open Data
2-Load any tile set

Setup Details

Used UndertaleModTool_v0.6.1.0 (not single file)
Windows 10 22H2 64-bits
Deltarune and AntonBlast
