I made several drops in lancs last night with no problems with accuracy...
I did notice that there seems to be a split second delay between the time I pull the trigger and the time the dropping noise occurs (before this patch it was instant) but this does not seem to cause any accuracy issues... I choke it up to the new sound system.
Actually, all sounds now seem to have that split second delay, but I'm talking hundredths of a second here... nothing to get overly excited about...
