[Enigmatica 6]
[Modifications: Spark serverside]
[1.16.5 Forge]
[Server: Yes]
[Players: 3]
Issue: Whenever using Chisels and Bits diamond chisel, when I click 'R' to scroll through different chisel selections, and select any size of chisel selection bigger then the tiniest option, my frames dip alot and when using Sphere my game crashes completely. I average around 120 fps with a high-end GPU (4060) for reference while on the server at peak times.
Screenshots:
When using Medium Cube option:

When using Large Cube option:

When using 2x2 (i think) Line option

This issue occurs with no players on except me on aswell, so it it not serverside. Spark profiler cant find it (/sparkc and /spark) for some reason.
EDIT: After testing a little more, when I crash its because my client does not have enough RAM, despite the fact it has 8gigs and anymore actually makes the client perform WORSE. (java garbage collection)
