I noticed a slightly different bug with Follow Through. When I use Follow Through (from Minotaur Axe) in the last round of a fight, the first round of the next fight it does not activate. The same thing happens with Blade Storm, Bonnie's Double Tap and sometimes with First Strike and Riposte. If they were used in the last round of the previous fight, they do not reset for the next fight's first round.
Similarly, if two First Strike (of a Rank 2 First Strike) were used in the last round of one fight, only 1 will activate the first round of the next fight, etc.
This was a bug I've reported (minus Follow Through) from before the new update went to test realm, but it was not fixed. (I did not report it on this forum, it was through the Contact Us tab of the website.)
