Other MCM tasks are validating fine. Both these WU also had a wingman turn invalid but hae both since been validated. I just hope this won't occur anymore since given the CEP2 limitations and the FAHV recent long intervals (over 3 hours in some WU's I've seen) , I won't really have much choice till a new project arrives.
