I am playing a save with K2 (no other overhaul mods, just QoL), but I can't actually add any input belts of raw imersite. I am able to get rare metals and mineral water, though, so I'm guessing it isn't a full incompatibility with K2. I tried adding another level of "Extra imersite" (going from 4 -> 5), but that didn't give me the option to add any imersite in the controller.
