Thanks to Lucidity was nailed true and genuine syntax bug in combining groups procedure (so affects only this rare situation). This will be of course repaired in next wip, but if someone do not want to wait, shouldn't activate this feature (is off by default) or, if uses script version, can repair code for each used Leader on his own - this is trivial. Broken is 111 line of HQReset.sqf:
_ex = (RydHQ_Exhausted - _x);
...or de-pbo addon version, do same correction and re-pbo.
_ex = (RydHQ_Exhausted - [_x]);
