Do you have a specific mod or mods you can reliably trigger this with? This has not happened to me when I was playing ATM10 and I am not sure whether it is a bug on us, per se - the mixin that is referencing is relatively simple and I would need to see the other mods' code to figure out what the combined issue is.

No mods that i can think of.

It could be caused by pregenerating the map though, as i remember we loaded a 10k radius and whenever we started exploring new chunks that came up and had to delete the unexplored chunks entirely.

Can you test to see if that's the case and report the pregen mod used? I'm quite surprised this is causing this many errors, considering I remember basing it on the Create solution to the problem.
