(Just making this a new post)
Here is the Eagle bug, including video, from the bug thread: Official KI Bug Reporting Thread Season 3 - #2731 by xFAxDRAGONKING @TotalJimkata
It doesn’t look to quite be the same thing (you have to hit the opponent with slide and then cancel veeeery late into ultra, they are able to block the ultra because the first hit doesn’t connect fast enough), but it’s probably worth looking into if the fix is easy (my guess is make the first hit of ultra come out faster?).
Also, in case the devs missed it, I calculated the frame advantage for all characters after a combo breaker. There are two particular problem cases that should probably be looked at (Rash is massively plus, Wulf is massively negative) if it’s in your guys’ scope, plus the Rash LK auto-double bug that makes him able to link any special move or heavy manual after. Thanks!
