.Map :: MoHAA Mapping

I am trying to add a usable Nebelwerfer in a multiplayer map.
I have added a working Flakk cannon, by choosing Turret Weapon, German, Flakk 88.
But if I do the same and choose a Nebelwerfer, although it appears ok when I run the map I can walk straight through it and can't use it!
How can I fix this!?!

you can only use the winter neb as a weapon

Yeah, only the winter neb was useable. But maybe u can change the tiki of the normal nebelwerfer with the winter one.
