Hello,
when i load all your mods, all of Space Exploration mods, K2, 248k Mod and omni library with omni compression and omni fluid i get this error https://imgur.com/a/FQB6IQz and https://imgur.com/BzS52Uf. It crashes with either K2 or SE
the mods i use of yours are: Aluminum, foundry, graphite & diamonds, lead, Natural Gas, Silica & Silicon, Tin, Titanium, Tungsten and Zirconium.
but when i load your mods that i have listed with omni fluid and compression it it works fine, but when i add Space exploration or K2 it crashes.
ps. I figured it out....its the setting Reuse grinding grit and fullerenes & nanotubes that causing the crash
