Patch 1.34 Broke High Command?

[bigshot 64]

I've just noticed a glaring issue with High Command. If I tell a private grouped unit (not in HC) to mount a static weapon...he'll stay mounted and use the weapon. BUT...when I switch that same unit into HC (while is he still mounted) he suddenly dismounts the static weapon. This never used to happen in 1.32....he would always stay mounted in the static weapon after switching him into HC mode.
