Tables Card, Piloting Skill Roll table, 'Mech Actions section
PROBLEM: It is possible to for a 'Mech that lost a leg to run using minimum movement rule. As far as I can tell this should cause a PSR. See my reports on the issue in AGoAC and BMM errata threads for more details.
SOLUTION: Add "Run with a destroyed leg (using minimum movement rule), except if already made a PSR to stand up" to the list of conditions causing a PSR (possibly in or below "Ran with damaged hip or gyro" line).
Xotl: I just sent this off to reprint yesterday, so it will be a long while before this gets noted. But the reprint errata line begins here.
