Issue isn't reproduced with spongeforge-1.12.2-2838-7.1.7-RC3785.

hello i have the same problem.

I am too
The people at SpongeForge are saying it's this mod doing it.

It is not right to pin the blame on this mod. SpongeCommon has introduced new and substantial changes to ChunkProviderServer - a core component of Minecraft, also modified by this mod. These could not possibly have been anticipated when this mod was written and are incompatible with the current set of changes made by this mod.

Understand that this should not be considered a bug report, but a feature request. This requires at least one new core mixin to be written for use only when Sponge is running, and will require not insignificant time to develop and test.

I agree, we'll debug this more on our end. Your change to ChunkProviderServer isn't significant.

I said I'd look into this and so I did:

#79

@Zidane fixed this, I'll make a new CurseForge version in a few hours!

Is there any update?
