After playing your (great) game for a while, i had this issue too. The weapon system had been slowed down, but driving around was possible at perhaps 25-50% of normal speed. I often discovered two (or more) bots crashed in each other, not moving any more. Killing one (or with a bit luck both) of them resolved the issue.
In other situations, this behaviour seems to be related to self-healing bots. Killing the affected bot made the game running normal again.
