GregTech CEu Version

GTCEu: v2.8.7-BETA / GCY-M: v1.2.8

Modpack Used

N/A (Self)

Addons Installed

Gregicality Multiblocks (GCY-M: v1.2.8)
GregTech Food Options (GTFO: v1.11.0.1)
Chisel (Chisel: MC1.12.2-v1.0.2.45), I'm writing/including this here even though it's not an addon because it was a Chisel block that I used, read below / scroll down for more details.

Environment

Single Player World

New Worlds

Yes

Cross-Mod Interaction

Unsure

Expected Behavior

The lighting should be identical to the original block (Not as a GTCEu Cover and/or Cover/Facade -type from any other mod(s)) when placed in the world (/dimension).

I have added an image to show what happens versus how it should be and/or look. The surrounding area is very well lit (Torches everywhere atm lol).

Actual Behavior

Actual behavior can be seen above and in these images below:

Furthermore; this is the actual block that was/is being used in this scenario:


(Cobblestone) (Chisel (Mod))

Same result but with Vanilla Cobblestone too 😔:

Steps to Reproduce

[Start]

1. Craft your GTCEu cover with Cobblestone (Dent) (From Chisel (Mod))

2) Choose where you want the aforementioned cover to go/sit-in-place.

3) Place the cover.

4. Reconnect the Cable and that's how You replicate the lighting issue, see images above!

[End]

I also tested this on a newly made (Creative) world and in one of My dimensions in My current SP World, both of which still gave Me the same result with both of the aforementioned block types; Chisel based Cobblestone (Dent) & Vanilla Cobblestone.

Feel feel to ping Me on Discord (XIPureGamer) (Nier Automata 2B Avatar :3 , same as here on GitHub) at any given time for any additional information and/or requests / etc.., I am always online and would be happy to help further if-need-be 😄👍

Correction: Only happens when horizontally placed in the world, not vertically it seems 🤔 Dunno why I didn't think to check vertical orientation sooner lol (..oops).

Hello again to whoever reads this, just wanted to add a couple more pics in addition to what's posted above, it seems to be happening on the vertical orientation now xd , I have no idea why... thanks Minecraft Rendering (not!), but anyway here's the pics/examples:

The lighting difference is a bit hard to tell in the first pic (Without conduits) but I can assure whoever's reading this that there is a (unexpected) lighting change, lol.
