All I know about the crash is that my harvester crashed me upon rendering.

Try it without optifine.

I think I might've given the wrong crash report, since this happens even without optifine.
This should be the report without optifine
Edit: Also, this crash happens on a modpack called ATM5 v2.5, harvester didn't crash me in v2.4, not sure what exactly is causing the crash to happen, but something that got updated/changed causes the render crash.
Edit2: Here is a picture of my harvester I use

Edit3: After testing a bit, it the crash seems to be caused by PneumaticCraft Omnidirectional hopper being on the contraption, seems pneumaticcraft-repressurized-1.15.2-1.3.1-39 version changed something and that change causes a crash when the hopper is in the contraption since pneumaticcraft-repressurized-1.15.2-1.3.0-33 was fine.

Yep, it's PneumaticCraft - my fault, sorry about that. Next version will fix this.
