If I have double in my inventory what the workbench asks for, then the enhance task will complete. So if the workbench ask for 1 computer chip, then I have 2 computer chips in the inventory. I was able to get a party bot to enhance level 10 this way, just by making sure I had double of everything the workbench asked for…
Yes, I have this problem. At first I was thinking it could be a mod causing the problem, then removed ALL of my mods except MCCC, and still had the same problem. The tune-up option works, it is just the enhance that doesn't.
