While I was battling against the Roarmulus Twins, the Auto-Lock On somehow doesn't seem to be targeting one of the twins during battle and not showing their health bars for some strange reason. It really annoys me.
Also, I had the Auto-Lock On and Display Monster Health options enabled, I think, but the Auto-Lock On doesn't seem to be targeting enemies for some reason, and the monster health bar display on the HUD doesn't seem to appear, too.
Could you fix these problems, please? Thanks, Three Rings!
This is already in the laundry list of bugs. Meanwhile, try pressing shift (or whatever you have toggle AT set to)
