OK, so hear me out. This post might seem long, but that's because I have provided 3 scenarios in which the bug occurs, so enough data is available.
I was able to reproduce the problem with a bare gamemode to eliminate as much variables as possible.
Bug tested with standard npcs (which is why I use gl_npcs.pwn), but I don't see why it should have any different result with real players. I can't test it with players, because I don't have enough people available. If some can reproduce this bug with real players, please comment below.

Server info:

• OS: Windows
• SA-MP version: latest
• Gamemode: test.amx (contains nearly nothing, see below)
• Initial filterscripts: gl_npcs (changed next to nothing from initial script, see below)
• Plugins: /
• maxplayers: 50
• maxnpc: 40

Complete test.pwn gamemode:
As you can see, we use just 6 vehicles in this gamemode (the amount of vehicles doesn't change the results, so 6 is enough).

gl_npcs.pwn filterscript:
The only thing I changed from the script delivered with the server download, is the vehicleIDs the npc's use. Keep in mind that vehicleIDs start at ID 1 not at ID 0 like everything else.
As you can see, only 6 NPC's will connect to the server and they are put in the first available vehicles.
If there are say 20 vehicles and the npc's are put in vehicleIDs with a few unoccupied vehicles in between, the results are the same.

Код:

//The original script had these lines in OnPlayerSpawn
PutPlayerInVehicle(playerid, 1, 0); //TrainDriverLV (trains consists of the engine + 3 trailers)
PutPlayerInVehicle(playerid, 5, 0); //TrainDriverSF (trains consists of the engine + 3 trailers)
PutPlayerInVehicle(playerid, 9, 0); //TrainDriverLS (trains consists of the engine + 3 trailers)
PutPlayerInVehicle(playerid, 13, 0); //PilotLV
PutPlayerInVehicle(playerid, 14, 0); //PilotSF
PutPlayerInVehicle(playerid, 15, 0); //PilotLS
//Which I changed to these (because I only use 6 vehicles in the testscript)
PutPlayerInVehicle(playerid, 1, 0); //TrainDriverLV (we use just a normal vehicle)
PutPlayerInVehicle(playerid, 2, 0); //TrainDriverSF (we use just a normal vehicle)
PutPlayerInVehicle(playerid, 3, 0); //TrainDriverLS (we use just a normal vehicle)
PutPlayerInVehicle(playerid, 4, 0); //PilotLV
PutPlayerInVehicle(playerid, 5, 0); //PilotSF
PutPlayerInVehicle(playerid, 6, 0); //PilotLS

The steps I took:

• Start the server
• /rcon login (I have playerid 6)
• /specvehicle (vehicleID is 1, as shown in test.pwn. Used by npcid 0, as shown in the code above.)
• /rcon kick 5
• /rcon kick 4
• /rcon kick 3
• /rcon kick 2
• Everything works fine up to this moment.
• /rcon kick 1 (this is the npcid just 1 ID higher than the npcid that was inside the vehicle I was spectating)
• Spectator (me) respawns. Even though I was spectating the vehicle, not the player!

Now ok, here is another similar scenario where the same bug occurs:
Changes to first scenario:

• 7 vehicles instead of 6.
• Bots are put in vehicles starting from vehicleID 2.
• So this makes that vehicleID 1 is not occupied by anyone.
• /specvehicle spectates vehicleID 2, because vehicleID 1 is not occupied by anyone.

The steps I took:

• Start the server
• /rcon login (I have playerid 6)
• /specvehicle (vehicleID is 2, as explained above. Used by npcid 0, as explained above.)
• /rcon kick 5
• /rcon kick 4
• /rcon kick 3
• Everything works fine up to this moment.
• /rcon kick 2 (this is the npcid just 1 ID higher than the npcid that was inside the vehicle I was spectating)
• Spectator (me) respawns. Even though I was spectating the vehicle, not the player!

Ok, so another scenario where the same bug occurs:
Changes to first scenario:

• Still 7 vehicles instead of 6.
• Bots are put in vehicles starting from ID 2.
• So this makes that vehicleID 1 is not occupied by anyone.
• /specvehicle spectates vehicleID 1, used by no one, where as in scenario 2, it was vehicleID 2, used by npcid 0.

The steps I took:

• Start the server
• /rcon login (I have playerid 6)
• /specvehicle (vehicleID is 1, as explained above. Used by no one, as explained above.)
• /rcon kick 5
• /rcon kick 4
• /rcon kick 3
• /rcon kick 2
• Everything works fine up to this moment.
• /rcon kick 1
• Spectator (me) respawns. Even though I was spectating the vehicle, not the player!

Conclusion:
I have no explanation for this. I am spectating the vehicles, not the players. So why do I stop spectating when I kick a player that is not even in the vehicle I am spectating? Even though kicking the player that is in the vehicle I am spectating, doesn't stop me spectating. I have no clue what's going on .
How did I stumble upon this issue? I am creating a spectating script in which I use some bots to test the script.
