The bug isn't really yours to fix. I remember mentioning Doom's swim animation a long while ago.. which was borked by id. Well I was running around in third person again, using different models (looking at all of them just for fun), and noticed that Klesk suffers from the same fate as Doom. They are the only two.
As for the request, it involves the Q3 lightning gun. All my running around was done in vanilla Q3.. and I dunno, the lightning was prettier. If I remember, it's a setting or something that you can change.. *goes to do research*... yea... cg_truelightning 0.5 ...activates the new(er) lightning effect. I think it's turned off by default, but it's there.
