Hanf_Kung , I first saw you randomly Disappear and Show yourself in deferent places & got a report on you.
In order to make sure you're not desynced , I was watching you minutes before your ban , you were riding a Police vehicle while not being a Cop , I 'Ejected' you out of it & then you made a Teleportation right inside LSPD , then i watched you getting outside LSPD again and riding a vehicle , I 'Ejected' you out of it again & you Telported back to LSPD & always keep moving , like Get out of LSPD , move freely in different directions 'Not bugged' and Ride a vehicle.
This happened 3 times, i ejected you out of the vehicle 3 times to confirm that.
Later after you were banned , i also received a PM from a player saying that he saw you TP as well.
Like you said 'I Took a car from Jyzzi' but no, that wasn't me who Jailed you , That was Admin [GSF]Traser who sent you to Admin Jail because of your Constant Car Jacking.
Normally after the 'Ajail' you may see yourself hanging up in the air but later on the world build up & you are back at your last Spawn point.
Considering what you said 'I restarted the game' , if that happened , will show in the logs alright , You said 'I restarted the Game and i'm banned'
The logs will show you enter that Vehicle 3 times , Entering LSPD as well before you got banned .
Throughout the 3 times i ejected you , you didn't seem to notice anything wrong ? , like stop , Contact an Admin or anything?
Good Luck.
