Today I accidentally caused a bug to occur in the leve quest 'Escape from Cell D72".

The second set of crabs were a little further back than they normally were (Lower part of 5,2 rather than upper right corner of 5,3) and turned into imps. I was KO'd by the second imp after having killed the first, and upon returning I found the remaining imp frantically moving in circles as if it had aggroed despite never going near it. After weakness wore and I engaged it, it continued this erratic movement pattern, never once stopping to attack or perform any of it's weapon skills. I was able to KO it, complete the leve, and received slightly less Skill. (336 for normal kill, 288 for glitched kill.)

I'm unsure how this bug was created as I hadn't seen this happen in all the times I've done the leve.
