Confirmed, can reproduce without trouble. Err...I don't even know if this is intended or why would it be this way. Interesting :)

This was also sort of happening when i was pressing "s" and then a direction key like "2". So when I searched and moved it was fast animation.

Also there was the normal animation problems with too many monsters on screen in IQ:5 and animated forest. And the guaranteed greater vault in fgjc.
