TTT Events

I’m making around 5 events for TTT. I’ve got most of the code done but I’m having an issue making it so that there are no karma losses or gains. How does one disable karma (these are rounds like Headshots only and other FFA style rounds) for that round?

(Seems like this should be simple)

Save the Karma to a table on the TTT begin round hook and restore it at round end?
