i crash at 1/4 of the chance when trying to get the guns from the locker.

That's just the common LSPD issue, I'm sure it doesn't happen anywhere else but in the LSPD. It always crashes when there is action in there such as players shooting and other weird reasons.. Anyways, This is already known, Maybe evidence tampering is one of the reasons along with shooting that make players crash.
Not something I can fix I don't think. Never happens to me, I don't hear it mentioned often etc.
