Description version v. 1.3.6.4b- Construction rigs can upgrade once again. Was bit by false positives from a security check added. [NM] - Extra work to ensure out-of-syncs are noted and reported. [NM] -- 1.3.6.4a build - Move score CRCs into per-timestep state checks. This simplifies items to track, is a net deletion of code, and should hopefully fix the issues seen with false positives on scores out of sync. [NM] - Slightly better cleanup of AttackGroups() when a unit is destroyed. Shouldn't ever allow a dead object to be chosen for a group leader. [NM] - Fix root cause of score desyncs; was switching tracking of kills and deaths for clients. [NM] -- 1.3.6.4b build
