Characters who's initiative counter has already went (whilst KO'd) that are revived that round instantly get to take their turn and act.

Person A has 50 cel ( 49 or whatever initiative counter), and is at 0 HP
Person B has 20 cel
Person C is an enemy that acts on 30

The initiative counter will look like this

Person A (KO'D)
Person C
Person B

Person A will get skipped, it goes to C, then B.

Person B casts SECOND CHANCE on Person A.

Person A will then get to immediately interrupt Person B's turn and get their own turn (with the KD/whatever needed)

Not sure this is a bug unless slower players don't get a turn at all.

Either way, the right solution would probably be to make revived people automatically skip.

[Rendar]

The turn order resumes, as normal, after the KO'd person now gets their turn.

Having them act as if they had skipped is probably the better solution to stop this.

This isn't really a bug. The game will choose whoever is faster after every action to be the one who makes the next move. If you took your turn, and your CEL were reduced by an effect, and it made you slower than an enemy who still had actions they could take, they would act before you could finish 'your turn'.
