Runemods float then sink into the ground
 

I just installed the rune mod and have a problem. The runes float and slowly sink in about 20 seconds and fall into the ground, when the bomb is planted it does the same thing so CT's can't defuse it. Also, you can not throw a bomb or kill anyone. If I disable the runemod, the problems have gone away but I have no runes now. :cry:
Obviously, I did something wrong but can't figure it out.
