Live, IOS 1.8.1 build 244
Saw this yesterday in game, was early in the spawn time so nearly 22h (21:45 would be the best estimate I can make) 9:40 AM PDT on 11/20/17. Seven Days Departed alliance.
One attack was duplicated (to a total of 3 times) in game on the display: exact same damage and exact same timestamp.
I think though I didn’t record this explicitly, that two slightly later attacks (a flask was used) were reported as this attack repeatedly. It did not affect the score, and a client application kill and restart corrected the issue. @loorts has seen it as well on a difference occurrence in his alliance, and might be able to add some more information.
I’m sorry I documented this badly: I have pictures posting the duplicate attacks, and I don’t recall there being hits after that, and then I can just barely make out the at the back end of the event log the real attacks.
Corrected attacks (sorry best I can do after the fact):
