Hello, Unfortunately, I do not manage the server part, but I had the crash report.

The crash happened when I put items in the "terminal crafting essential" of thaumic energetics, I'm not at all stable in terms of FPS, I go from 120fps to 3fps.

When I type a specific search, I go back to 120fps.

When I try to craft an item, it takes more than 30 seconds before the item arrives in my inventory, if it happens before there is a crash server

It looks like a loop between a Essentia Storage Bus and Essentia Export Bus. Could you please provide more information about your setup?
