Okay, so...
I was exploring in Astryl's Meadow when suddenly my character froze up. I couldn't move around or anything, so I decided that I would ignore it. Bugs like this have always fixed themselves after a while for me.
So I decide to go to my inventory, because I had gotten some armor and I wanted to use that. But when I clicked on it and tried to give it to my Sylesti, a notification popped up saying: "You cannot manage your inventory during a battle." So I was like, "Well, maybe I forgot and accidentally left a battle open." So I went into the world map and clicked on the area I'm currently exploring. Instead of going into that area, it brought me to Astryl's Meadow...in the exact same spot I had been...with my character still frozen.
So now I can't manage my inventory, can't explore anywhere, and are still frozen in Astryl's Meadow. Help!

Okay. I just realized how stupid I am.
Apparently, I had encountered an enemy off screen, and that made it so I couldn't move. This wasn't a bug at all, just me being stupid, like I am sometimes.
Ignore this problem! It wasn't a problem at all!
