It seems like EnderIO Pipes can occasionally cause an Thread unsafe action resulting in a freeze of the game after a while. (Ender IO Pipes in this setup: EnderIO Pipe piping into Furnaces with a Filter Module on the back and out from the top the items are mainly Dusts produced in SAW Machines from Ender IO)

Version: 1.10.2 newest Release of TechReborn
Screenshot: Not Available

I sure do have power cables from TechReborn in my World but the error only happens if i try to use Item Pipes from other mods with TR Machines. The game is stable as long as i dont have these around TR Machines.

I'm having the same exact error with Mekanism Item Pipes Latest Releases from both again.
At least this time i could see the error more directly happening.

I put a Pipe above an electric furnace, i changed one of the Pipes sides to NONE so it doesnt interact with a chest next to it and instead only sends item in the top of the furnace. After that => Game freezes

Please fix this as a hot fix its really game breaking in my opinion.

It seems to be an issue with our multipart api, so you have any power cables from TechReborn or FluxedRedstone in you world?

The log also mentions CCExtendedBlockRendererDispatcher so im also going to ping @covers1624 to check its not his core mod wizardry breaking this.

Nope, if it only sniffs the model being rendered and then handles it internally, if it falls back to the Vanilla renderer in the stack then nothing of mine is executing.

And, its not even done with a coremod, just a parent overriden BlockRenderDispatcher with reflection to replace the instance.

Ok, great, just wanted to check it wasnt you before I start poking around trying to fix this.

Do you have optifine?

Yeah, you do, remove that.

To test it out or is this a general incompatibility?
Cus i need ma optifine yo. [< not an attack just a joke yo]

Will test it even so.

seems like it works fine at the moment, i also saw that i used that i am using an outdated optifine version (1 behind which came out a week ago) i just don't know if it fixes this specific issue.

I think its been fixed in the master mcmp, I will need to update that and that should fix it.

Let me know if this is an issue without optifine and I will reopen it.
