Started a new campaign from after the 64 bit update, fresh install, no old saves, clean start.

However, most ISD models (ISD 1, Procusator, for sure) seem to have bugged targeting, either only firing at point blank range, or trying to do 360 degree turns to "target" (and failing halfway through, and then trying to return in a random direction.) Only sometimes do they target when facing broadside, rarely at max range, usually only at laser cannon ranges, sometimes they fire at strange angles only, sometimes not at all.

I know it's not just me being a poor player (using them facing straight on, instead of broadside, for example), because the Vader ISD (Devastator) is working properly, firing whenever the target enters the max range within a proper firing arc. This is the first time I've encountered this issue, so that makes me think it's related to a "fix" within the 64 bit patch, but who knows, I haven't played in a few months.

Cheers!
