Hanging Signs From the base game (Modded signs do not have this behaviour), Will have a 'ghost' normal sign of the same material behind them. It doesn't have collision, Or any other behaviour. Fuck'n odd...

Confirm

• This bug report is about an issue with the modpack itself. I have not modified the mods nor added any resource packs. If this is not the case, I know that I should post the issue in the #perpendicular channel in the ParallelMC Discord server.

Optimized Block Entities is conflicting with another unknown mod; it doesn't cause this issue by itself. The real culprit is likely a mod in our pack that modifies hanging sign behavior to some degree.

As a bandaid fix, we'll just disable OBE's hanging sign optimizations for now while we keep investigating which other mod OBE is conflicting with.

Turns out it's an incompatibility between OBE and Platform, the library mod behind Vanilla Backport - I reported it here: maDU59/OptimisedBlockEntities#57

We'll keep OBE's hanging sign optimizations disabled for now until OBE / Platform fixes the bug.

If this only happen with Platform and not without it, then I believe this is an issue on their side

I submitted a PR to Platform with a fix:
ItsBlackGear/Platform#23

They are modifying how a method used by OBE to differentiate Signs and HangingSigns and used an incorrect class name. Every class extending SignBlock was being reported as a non-hanging Sign block entity, the issue is HangingSignBlock does extend SignBlock, they should have used StandingSign instead. This is probably due to porting to another MC version, I believe SignBlock have been the name of the class for the standing signs in the past.
