Block holes with OF+FTw

[AnrDaemon]

Both blocks are ~regular wooden planks, no different than the rest on the floor~ EnderIO-painted Glowstone. The issue is consistent across relogs and persist without OF.

A short list of mods:

EnderIO-2.8.4.jar (GTNH fork, but reproducible with stock one) falsepatternlib-mc1.7.10-1.2.3.jar falsetweaks-mc1.7.10-2.8.1.jar

[FalsePattern]

Does it happen if you remove the XRay mod but keep optifine?

[AnrDaemon]

Yes. It happens in any combination provided FTw is installed. Even if it installed alone. I can't think of anything specific with these specific tiles, there's no light emitters in these places (the roof is just wooden slabs, all the light is from two skull candles, one you can see and another further back and to the left), there's not even anything of interest directly under these tiles.

Mystery solved! 😊 It is an EnderIO-painted glowstone. It wasn't showing itself with yeta wrench, so I assumed there's no trickery. But actually breaking it yielded the block with suspiciously recognizable markings… so, yeah. /blush
