@stillhere Interesting, I'll check it out, thanks! But at any rate, it's a relief it's not a problem on my end, and I also wonder why I've never seen this "problem" brought up before, I searched the GTA forums a fair deal before I gave up on it.
Also, if I recall correctly, as of a couple of patches ago, Rockstar also added a little "feature" that despawns the new cars they added for GTA Online - and then I don't remember if it was either ScriptHook or the Community ScriptHook that removed this little annoyance. Weird that they couldn't have done the same for the weapons.
