After placing the Fluid Generator in TechReborn version 1.10.2-1.4.0.35 it will cause a ton of FPS lag.

Working fine in newest build

Do you mean the semifluid generator?

Ok yeah, it does

I think this needs a bit of optimization: https://github.com/TechReborn/RebornCore/blob/1.9.4/src/main/java/reborncore/common/tile/TilePowerProducer.java#L41

EDIT: Removed, created new issue

Yes please, I will go through the issues after TMT
