When called after Team.PlayerRemoved fires (if the player removed leaves the team by leaving the game), :GetPlayers() will include the player removing. Otherwise it won’t
This is a very specific bug with the Team API. The following conditions must be true:
- The player is on the team
- The player leaves the team by leaving the game
There’s an consistency between when the player leaves the team via .Neutral, and when the player leaves the game by leaving the game. Both situations fire Team.PlayerRemoved. However, a call to Team:GetPlayers() will report the team as not having that player in the first situation, whereas in the second situation, the player will be reported as being in the game.
When Team.PlayerRemoved is fired, normally the player is not included in a :GetPlayers() list, however, when the leaves the game (firing Team.PlayerRemoved), they are included in the player list.
local function inList(tab, val)
for _, item in pairs(tab) do
if item == val then
return true
end
end
return false
end
team.PlayerRemoved:Connect(function(playerRemoving)
local players = team:GetPlayers()
-- Assertion fails in second case (player removing from the game)
assert(not inList(players, playerRemoving), "Player should not be in list")
end)
Repo
Normal behavior
- Listen to Team.PlayerRemoved
- Assign player a team
- Remove player from team while player is still in team (Switch Neutral = true)
- Behavior: Players:GetPlayers() prints out no players
Player removing behavior
- Listen to Team.PlayerRemoved
- Assign player a team
- Remove player from team while player is still in team (kick them out of the game, let them leave normally, et cetera)
- Behavior: Players:GetPlayers() prints out the player object in the PlayerRemoved listen
Repo place
Attached is a repo place where you can see this behavior fail in person! Notes:
- Simulates player removal by
:Destroy(), but the case reproduces in live gameplay too*

This is an obscure bug, but one that is currently breaking my game.
