I got the following error today, randomly while taking out personal reactor from an assembler using shift click. Error comes randomly. cant figure out how to reproduce. earlier this error happened while taking out personal roboports from another assembler.

The mod Quantum Fabrication (2.4.15) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event quantum-fabricator::on_nth_tick(9)

Ok this keeps happening more and more now, I cant play anymore because the game keeps crashing when i take stuff out from assemblers

Please upload your save somewhere, I'll check it.

Edit: nevermind, got it. The crash happens when trying to insert/remove thing to an equipment grid via item requests. I guess I kinda forgot that this is a thing. I'll fix it in a bit.

Sorry missed your message.

So the issue was with equipment grid item requests, i just wont use it for now while you update the mod. Thanks a lot! <3

Alright, I added a bandaid to hopefully fix crashes. Item requests in equipment grids won't work until I figure out how to implement them, though.

Thanks!
