Edit: Disabling Alien Biomes seems to have resolved things.
Same error. It loaded once successfully, then began erroring when I changed the system seed from all 3's to 123451234. It's sometimes changing which mods are in the list as problematic (i.e. Diurnal Dynamics pops in and out as I fiddle with things further) but planetslib and vicrox are consistent.
