Failed to load mods: Error while running setup for entity prototype "electric-mining-drill" (mining-drill): next_upgrade target (kr-electric-mining-drill-mk2) must have the same collision mask.

Seems to be problem with latest maraxsis update, downgrading it to 1.30.67 should fix the issue

yeah, that was the case for me too. and other thing. this is happening not the first time. same error gets thrown out when maraxis updates. he needs to fix it on his end. as i love k2s0 pack :) just disabled maraxis mod and will play without it. as it is not worth risking my save file.

For me it was enough to disable mining drones ( if you have them )
edit: But also Enabling mining drones and disable maraxsis works too
