If he cant do anything which I highly doubt but maybe its something to do at the beginning which i dont remember since I've finished the game long ago, then its probably in the wrong row. If you press X and go back to battle options when your turn starts, you can see the row option. And you cant accidentally skip the turn if you want to skip the turn on your last member. Since you already want to do it. And If you are talking about accidentally skipping the first or the second members turn, you can also press left arrow key to get back to them or x If I remember correctly. And If you waste your chance to use the Row the first time by opening it and closing it back you wont be able to do it till the next turn. That doesnt make the game bad bruh.
I know what happened in my game that I was currently playing, not remembering something from long ago. I didn't "accidentally" skip anything. I explained what the situation was and even if I had opened and closed the Row command thereby nullifying it, which I didn't, that would still be bad design. Just to be clear it was not the first round of combat when this happened.
This situation could also have been resolved if you were able to save the game before the battle, but I couldn't because...I don't know...the designer wanted you to fight multiple battles in row before being able to save, I could have just reloaded the beginning of the battle and continued on.
Last post, as I will have moved on to other things. Good luck to the Dev.
