You can now disable texture repeat on LevelTiles without the material/UV breaking.

If you ever encounter strange colour bleeding at the edge of a tile, you must disable texture repeat on the material.

(The texture repeat setting)

Thanks to Rat King for this fix!

The only file changed is addons/codex/globals/lb_global.gd. If you want to upgrade from 1.1, just replace this file while Godot is closed.
