Keep getting this error after I changed my mana requirement, I had 109 mana, my minimum is 50, and I got this every time I entered a room with a critter, and the script ended..

[Lower Dragonsclaw, Forest]
There is a break in the trees here, several charred trunks bearing witness to a past forest fire or act of nature. A modwir lies across the ground, the scars of a lightning strike etched into its blackened trunk. Just near the remaining tree stump, you notice a dirt footpath leading south. You also see a rolton, a rolton and a clearing to the east.
Obvious paths: northeast, southeast, northwest
