One of the few negative things about the movement-event code was that it doesn't check the boundaries immediately after an event occurs, such as the Dwarf Base doorman. As soon as he gets back, you can "force move" into him in a brief moment before the checks are reapplied.
This has only one negative consequence that I can recall. After Tower of Babil Super Cannon event, you are able to walk into the door for a moment.. and then get stuck in the area.
In FF4A, you can perform the same event, although you repeat the Yang kicking your ass back outside... and repeat the cycle. I guess that's better than being perma-stuck.
We have EVEN MORE themes now, but some old ones are gone...
