Haya. I don't remember this being around last time I sparred with someone, but I recently sparred with a friend in order to damage them so their crafting timers would be higher. We started sparring, they took off their weapon mid-spar, and it ended with me winning. I reselected them as a target out of habit, and it let me "win" a second time. Then a third, and after a few times I managed to wound them once again despite having already won multiple times. This could be continued on and on, and I could continue either wounding them or "winning" 5 minutes later as well. We tested it a second time, with the same results. As far as I know we didn't do anything special to cause these results, so I believe that sparring is simply a bit buggier than usual right now.
