It was the ALCOR pod, but included in the CMES mod. I got rid of Chaka and am trying the 'official' ALCOR mod - I'll tell you if the problem persists
Yes- the problem was after an IVA docking. After docking (using the CMES NASA port), I undocked, and the readouts on the docking screen did not change. i.e. reletive velocity, angle to target, etc. The master alarm was also stuck 'on.'
