THIS has kept on happening, although instead of advanced rocketry, it is now crashing from water strainers toml, and i checked and there doesn't seem to be anything inherently wrong with the file, except for at the bottom there is a random =false on it's own line after everything else
EDIT: I removed waterstrainers toml, and then advanced rocketry started erroring again, so I don't know what to do.

I've been having this same crash, whenever I am exploring in the world and generating new chunks. It also happens when I go to chunks I had already generated before updating. I didn't have the issue until v 1.3. Sometimes it crashes, other times all the mobs freeze, the world stops loading chunks around you, and you can't access inventories. The only way to fix it is to kill minecraft. Quitting and saving just freezes. I
I have no idea of a solution and the only thing I can find about a similar crash is from a few years ago. It had something to do with how AE2 resets the lighting in a chunk with a meteorite and it causes the vanilla lighting engine to freeze. I have no idea if this is a related issue, but it's the only "worker main died" bug I have found anywhere.
