Spiders problem

[Cranky Old Man]

I'm having a issue with spiders not moving around the room, no matter how high up I put them or if I put them on a surface, the model just stays locked in place moving around like its walking around the room, but it seems to be actually moving cause I can get hit by it across the room.

I remember that an explanation was given about raising some sorts of collision box in the model editor. Of course, this will mean that you will have to create a new version of the spider, or else your mod won't work on other peoples computers.
