I had the very same last week (made worse by the fact that I no longer had any memory after cl_beams...) and kinda hacked around it by doing a check for "if (cl.time < 0.0001) return;" at the start, as it only seemed to happen at a changelevel. I was never really happy with that solution, so I'm looking forward to trying this out and seeing if it resolves anything.
Thankingyew!
