So I talked with milkycow on discord and we tried to fix this. What we found out so far is that the error he is receiving is definitely caused by an object as he crashes when he goes in mapped areas(Clothing stores, electronic stores, etc.). We succeed to go into a clothing store and when he goes to a specific page which contains specific items he also crashes which makes me think it's one of those items that makes him game crash, as the items from the clothing menu where also found as spawned objects in the electronic store. The thing is, usually this happens when the gta3 or gta models are corrupted, but they're not, he tried 3 different gtas. The error he's getting sometimes it's 0.3.dl specific so I'm thinking it's somehow the custom models added to the server or custom models. He crashes in North Blueberry too. We went to the same location on single player and it didn't crash, so it's definitely samp objects.
objects that crash his game^
These are also found in the stores where he is crashing:
-Sensations
-Electronic store Montgomery
