That's most certainly interesting, given that nobody else has reported such an issue. I have a some questions on that note.
1: What sort of time frame are we talking about, before this occurs? Immediate, after 1/2 hour of play, several hours of play, or something else?
2: Is it potentially linked to player deaths in a respawning scenario? Like it starts happening after 20 player deaths or some such thing?
3: Is it potentially linked to the number of weapon switches?
4: Does it happen on both a dedicated server and non-dedicated?
5: Have you attempted to just disable the scripts, and nothing else, in order to confirm that this is in fact the problem?
6: Does this problem exist with v1.2?
