In my opinion, there was an error in the report; the standard desynchronization errors have long been identified. They occur when attacking units with area-of-effect spells (mages, liches) or when besieging a castle with an artillery unit in the garrison. It's clear that these have nothing to do with the game version (SoD, Lite, TE, WT). It seems that some even rarer case occurred here. In general, it's not worth paying attention to Navukha's (captain's) empty claims, as in most situations.
