[TF2] Force MvM robots into the spectator team when a wave has ended
 

I'm trying to host a Mann vs. Machine server for a few friends of mine, but the robots sometimes respawn after the wave has ended and carry the bomb while everyone is upgrading. If they're killed again, they repeatedly respawn until the next wave starts or they deploy the bomb. This only happens if Sourcemod is installed, regardless of operating system (tested with Windows 8.1 & Ubuntu 18.04.2).

Forcing the bots to go onto the spectator team with bot_command prevents them from respawning during the downtime period, but inputting this manually for each bot is not exactly feasible or efficient.

A plugin that forces the robots into spectating once a wave ends would be greatly appreciated. Thank you in advance!

EDIT: Just found out that bot_command has an "all" parameter. Whoops.
