exception when compiling collision

[vote1sanches]

I made superhigh, High, Medium, low, and ~damaged models of my scenery object, and they compiled fine until i tried doing their collision.

When i try i get:

could't read map file './toolbeta.map
### high.JMS
###Low.JMS
###Medium.JMS
###Superhigh.JMS
###~damaged.JMS

Exception halt in .\import_collision_bsp\build_collision_geometry.c,#146:vertex_addendum_index ==vertex_index

this is my first destructable scenery. What could I have done wrong.
