I´ve been getting an error message "Insufficient armor; task suspended" from within MHQ when trying to salvage armor off a wrecked mech; the log file for that one is attached. I have also occasionally got that message when repairing battle armor, if the armor stored is exactly enough to replace lost armor on a suit.
I've created patch 3490100 (https://sourceforge.net/tracker/?func=detail&aid=3490100&group_id=269041&atid=1144610) to take care of this bug.
The patch has been applied to the development branch and should be in the next release.
This bug is fixed in the current release
