Monster Ai (Help Needed)

[Bomberman]

So I have been testing with new character models for enemy's, and I have come across an error.

When ever the enemy runs towards me he gets pushed back by some force field. I am using the default

monster script.

I had something similar happen to me when going thru Aggrors video tutorial. When I moved near the spawning drums they would be repelled from my charracter. It was sometime ago but I think it was to do with the physics of the drums ( so enemy for you) or their mass.
