I was playing Op. Totalize on Wolfgaming's server today with about 12 people or so (mostly less than that).
Instead of a kit limiting error message on the selection screen, I could chose whatever class and spawn...then I would die.
Here's the issue: with no more than a dozen players, there was no way that the kits were being used completely. For instance, I know I was the only MG gunner (per the squad screen) and I was instakilled.
If this is a server side mod, I apologize for cluttering up the fourms. I've played Totalize on Wolf before and never saw this problem.
