Prior to the boards being reset, there was a ruling that a floating critical that rolled a leg location on a target behind partial cover would not be lost and would need to be re-rolled until it hit a valid location, as the critical result should trump the partial cover.
Can this be reconfirmed and added to the errata for TacOps?
Example output from a MegaMek game:
Weapons fire for Legacy LGC-02 (Bot1)
LRM 20 at Atlas AS7-D (Tathas); needs 7, rolls 5 : misses.
Medium Pulse Laser at Atlas AS7-D (Tathas); needs 4, rolls 8 : Atlas AS7-D suffers no damage. (LL (critical) behind cover)
