So you are saying that the issue is confined to the replay and not the game that I actually played?
I was wondering if that was the case, but while playing I deployed two turrets on the south side of the map, which I thought would end the two separate battles I placed them in, but both seemed to be shooting at the same target over and over - once it was a radar contact but the trajectory of the animation looked like it was heading to the same place every time (in the replay, it appears to be a building with extremely negative HP) and the other turret was attacking a lone reaper, last in the squad of 4, and allowed enemy drone MRV to take out my turret while it wasted attacks on the reaper.
When I watched the replay to critique my strategy, I noticed that the two turrets I deployed that "didn't win the battle" were in fact occupied with 'dead' units... as I seemed to remember happening moments before during the game.
I've noticed HP go negative before, but the unit dies within moments of negative HP... also 90% of my games are sub vs PHC and the first ranked sub vs sub game that I ever remember playing, was shortly after the 2.3 patch went live, and this happened. As a software developer myself, I thought I ought to report it (plus I really think I would have won that ranked game!)
Thanks for the reply, please confirm if this sounds routine, or if this is a known issue with replays.
