Entering Coil issue

I just joined a group for Coil and I hadn't finished turn 1,2,3 but I had started turn 4 with my FC earlier. I didn't know you couldn't go back and do the previous ones after u started a later turn, anyway, I joined a pug group and they wanted me to try entering the dungeon because it wasn't working (now obviously I know why), and I ended up locking everyone out of the previous turns because I queue'd all of us in for turn 4. We didn't initiate the start of turn 4 either. I feel terrible about this, and think this should be addressed. A simple pop up letting the party members know that they are about to enter this turn, would really be useful.
