Description of the issue:

Ok, so this is a bit involved.

I'm getting graphical glitches similar to #3293 (comment) and #2289 where the conveyor belt is checkerboarding, but the walls and geometry are rendering correctly. It's also ignoring placement direction and not moving items. Chutes are also affected but not covered conveyors. Existing conveyors are not affected. Unlike the above issues, this is an existing survival world that didn't initially exhibit the behavior.

This began either when I made config changes to unrelated mods (inventory gui settings in quark) or when I first placed a chute in the world & restarted the server. (I compared MultiMC pack exports to double check changes.)

This only happens with a dedicated server. It does not happen in my local test world.

I compared the md5 of my local jar with that published on CurseForge; they matched.

Per the above thread, I tried /blockdata.

Broken conveyor: {x:1727,y:68,facing:5,z:1706,id:"immersiveengineering:conveyorbelt"}

Old working conveyor: {conveyorBeltSubtypeNBT:{dyeColour:-1,direction:0},x:1779,y:42,facing:5,conveyorBeltSubtype:"immersiveengineering:conveyor",z:1693,id:"immersiveengineering:conveyorbelt"}

I've restarted everything several times.

Crashlog:

Non-crashing. There are no errors related to Immersive Engineering in the client or server logs.

I'm not sure this is related, but also chutes weren't putting items into dispensers before conveyors went all funky.

Again, works just fine in my local test world.

Oh, this looks very similar to #3580 so this might be a duplicate?

Note sure why it's infected my conveyors, or why that infection persists.

Ok, yes, it is a duplicate with #3580

The "infection" was actually because the chutes popped as things that look like conveyors in the inventory, but lack the NBT tags, causing problems. They're always glitched and will remain glitched.

Other conveyors still work just fine.
