I've added a new plugin into both Chocolate and Rainbow that will change the capture rules on KOTH maps. As I explain here!
This plugin is designed to toggle the cvar "mp_match_end_at_timelimit" if a team captures the control point on KOTH.
Previously, KOTH maps would end at the time limit no matter what; this was set in place because people who would choose not to cap would wind up holding the server hostage on a particular map.
The downside is that if a game began close to the "end" of the round, there would be no point in capping because the round would end regardless. This is now solved by turning this cvar OFF if the point is captured, and turning it back on during a new round.
Does it still work after the updates and all?
