Hello there!

I play with a friend on a local network with mods, but when I upload a chunk on which it is located (friend is host), the FPS drops to zero and this is logged in the logs:

Game version is 1.12.2

My list of mods.

 

1.12 is no longer supported on this forum. Please update to a modern of Minecraft to receive support.

I found a reason, this lags makes backpack mod, but why?

Okey...

Complain to the author of the mod, not Forge. Forge didn't write the code that is causing the problem so what do you think we can do about it?
