It would be really great if the duplicate bug reports would stop.

The comments posted here will be considered when fixing this bug as it's been tagged as duplicate.

that crash isn't even near the other one...

Sorry, meant #1567.

That's why I like having the actual crash in the ticket text, so you have a chance to find existing crashes without having to read 120 tickets back... ;)

Yeah sorry I might have reacted too harsh, but I am tired and I've seen this particular stack trace so much already on this tracker.

Then go to bed early and put a try-catch block around that point tomorrow until you fixed the underlying issue ;)

I don't like masking issues like that ;)

I'm sure people don't like their servers crashing either...

I don't really mind, but that's because I crash our test server all the time anyway, so it doesn't matter ;)

Hi I'm the user who keeps causing this. I'm essentially autocrafting essence for mystical agriculture using the phytogenic insolator from TE. It is a bit of a weird setup. Here are the things that I think make it different from normal:

Pattern has product on other side since seeds are needed (maybe some recursion weirdness?)
Crafting jobs are quite large (maybe 50 lots of seed, could be up to 1000 essence)

3 Crafters on 1 machine and thermal mediator (block from thermal expansion that speeds up adjacent TE machines). I don't think this should be an issue since it's not ticking the network as well but that could be the problem.

I'm happy to provide any other information about the setup if needed.

I'm going to go and test the thermal mediator now to see if it's causing issues, I'll report back if it does.
EDIT: Haven't found any issues when running three of them around an induction smelter constantly working so maybe it's not that.
