While looking closely at the 'hr-electric-mining-drill-N-patch' and 'electric-mining-drill-N-patch' the color of the lower pipe connection is inconsistent. Also, if you zoom in closely to the 'hr-electric-mining-drill-N-patch', the lower pipe connection has a brown area on the left of it while the rest of the connection is blue.

meh, minor stuff. what's really annoying is that i can't research MK2 miners because I already replaced all my basic labs with advanced labs xD

The 'electric-mining-drill-N-patch' lower pipe connection is still brown while the high res version is blue. The minor issue with the high res was fixed, but the inconsistency between the low and high res version is still present. Basically, only half of what I originally posted has been fixed.

Ok, ok. Someday I will fix it.
