SO...after having this functionality for 8+ years, it appears the "Smissmass 2016" update that changed the autobalance functionality has also broken the "swapteam" function our supporters have been able to use for years.
Specifically, the game no longer kills the player when they swapteams, it simply (and instantly) changes their team, which means people can create havoc by swapping teams in spawn, etc.
My question is - is this going to require an alteration to the underlying plugin/extension, or is this something that will be fixed in Sourcemod itself?
