Problem when there are around 20 players

[MrProof54]

Hello, I made my server Zombie Escape, I tested without problem, except that when I put bot to test if everything working came to 24 bots, the gamemode starts to bug, the game starts but a " Human Win "appears and the game continues but the Human Win does not come off during the whole game! Arrived at 30 bots, the party bug several not launch all the time but often anyway, 1/4 of the players die and a Human "Win" reappears! Arrived at 48 slots, any bug, half of the players die and respawn zombie and the Human Win is still there! I have to limit my server to 20 slots for no bug, can you fix the bug please? Sorry for my English a little bad but I try to express myself at best in this language, because I am French thank you in advance!

and If a player connects during the buying time and well the round goes bug
