- fixed single-use items in Melee that are not marked to be used from being removed at the end of the Melee
- removed the requirement for Spotting Round/FFE artillery targeting to be in visual range at night (was a rules misunderstanding; they just have to be in non-Blocked LOS)
- fixed opfire from being prompted vs. a buttoned armored vehicle when the opfire unit has weapons that can reach the vehicle that cannot affect it, and weapons that can affect the vehicle but cannot reach it
