[here's the list of my known issues for gta 3 and vc , its not too big and confusing and i tried my best to simplify them so it won't be confusing and be straight froward.]

for gta 3 (there's not much expect one major issue):

=>car explosions causing by players won't sync up with all players

=>sometimes peds animations don't sync very well( including cops and fighting peds)

=>the major and game breaking bug is the crash (Unhandled Exception) after getting busted by ai cops and if i'm not mistaken ,sometimes crash on respawning after death (note that it only happens to the players with IDs above 0, like 1 or 2 . player with ID 0 is fine , not even a single crash) . i've attached the crash dump

known issues for vice city :

=>player blips stay on radar after players busted by police and respawn at police station

=>ped animations won't sync with other players

=>parked cars spawn twice or more depending on how many players are in area

=>game crashes ( players above 0 ID , again ) when they get busted or even get attacked by police on foot on 1 star ( crash dump attached also)

=>spawned vehicles by players are only visible to them (happens for all games , not only vc)

i hope this report helps. also , I've attached the crash dumps and a few screenshots for better understanding just in case my report wasn't as clear as possible.
