Issue Description

Not a large world, pure modpack (no config changes or extra mods, not even shaders/optifine), UX video options turned down low for nearly all options (fast not fancy, 6 chunk render distance, ...) and not a lot going on (no large mobfarms, automation, etc). The industrial foregoing machines I do have consistently hang the UX - not lag but 100% permanently unresponsive. Moving the geothermal generator next to a machine might hang. Opening the gui of one of the machines (especially the dissolusion chamber) might hang. getting the WAILA heads-up on the mob slaughterer can even cause the hang. Never had the issue interacting with other components of the modpack (mob grinding, mystical ag, etc) and memory is running <5G out of the 7G I allocated. don't have a crash report since it just hangs, and no valuable logs.

While the UX is hung, sounds continue. Animal sounds, machine sounds, chickens laying eggs...things seem to be running.
[Esc] stops the sound as if headed to the [Esc] menu, but nothing displays. Hitting [Esc] again gets back the ambient noises but no UX.
Closing the entire client leads to chunk saving and when I re-launch the client I haven't lost anything.

maybe it is WAILA and not IF. Either way, I load up a world, I can walk up to the dissolusion chamber and just sit there doing nothing but looking at it, and eventually it hangs.

meh, just staring at magical crops this time waiting for them to grow, no input, hung anyway. got a good hour of life out of it this time at least. I get how this would be a really hard bug to track down, wanted an instance raised somewhere anyway just in case. I don't see this on any other modpacks btw (other skyblock/skyfactory, terrafirmacraft+, regrowth, etc)
