not sure, your one of the few people having it.

Why can you not spawn more than 3 of any Mech in a level? how would I fix that limit?
Its at 999.I have no trouble spawning as many other vehicles as I want.
My server is up, I put everything up to 999 and there is no difference.
Disable all your add-ons exept the mech then see if it works.
