Couple of subtle changes:
Removed the solo challenge thing. Now you can just play all the maps alone, to help you practice. Perhaps. Makes my life testing new stuff a lot easier
The zones on Follow the van start closer to the centre, but the spawns are the same. This means the have to chase the zones at the start and they meet a lot sooner. Be prepared.
And what Voodoo said. I've been caught by it myself. Adapt.
It was a case of the lesser of two bug types. You want the laggy wall explosions back? <-- that was caused by the amount to network traffic having to be sent to each client btw.
