Sometimes I can catch the thing shown below in the picture in WAILA, for a moment. It seems like WAILA displays the QmunityLib multipart first, then shows the actual tile (gate, wire, lamp, etc.)

It's just a little visual issue.

Yeah, we know about this. I've been working on the multiparts a lot lately and I think I've managed to fix this already, but I'll have to check. However, the fix isn't out yet and I don't really know when it will be since it involves a complete rewrite of QLib and a big chunk of BP

Okay, thanks! 😄
At least for now, I wrote a Localization for it with MineTweaker.
