gollark: No, you can manually install mods, but you need forge.
gollark: I can't actually tell. I checked in it very briefly, in it the machines tower is 1 floor.

gollark: It was backed up. It's just that my backup retention policy was broken.
gollark: This latest messup was probably mostly on me (really should test stuff better), but I have no idea how big modded servers run without exploding.
