Minecraft version: 1.20.1
Forge version 47.1.3
Rubidium version: 0.6.5

CreativeCore version: 2.10.31
LittleTiles version: 1.6.0-pre055

When LittleTiles is present in the mods list, normal redstone and many leaves turn blue with Rubidium installed. You don't have to use any of the mod to see these issues; simply place redstone dust down into the world.

check plz if this issue is still present on 0.7.0
