ROTDS beta testing

I did notice the poison tics were slower, but thank god for Poison anyways. Now, since it's been so long, are there any key items, or Espers, that are permanently missable? Edit: Ok, I have a problem. I'm not sure what caused it, but my game is broken. After I loaded a save state in the world map near Sabin (Or Ronan, I think) house, I fought two battles. On the way to the port, I fought a third. I went to the ports inn to heal, then the armor shop to finish upgrading my equipment. I walked outside, fought a battle, and Cloud gained two levels, or so it said. But then it froze. I managed to repeat everything, and it froze again. Edit 2: So, I tried to change around how I got my money, and how Cloud leveled up. I slept in the house, instead of the inn. I ran from a battle. I even tried going to Spiral Mountain. But no matter what, Cloud gains that double level, and my game freezes. I'm stuck, unless I restart.
