This script adopts W'rkncacnter's CTF script to the newer API. See the readme, the original CTF script, and the Magenta Filter maps for more information.
This release hopefully fixes out-of-sync issues. It also adds messages for all flag statuses (taken, dropped, returned, scored). There are also screen faders for these events. Finally, the alert sound no longer plays if a player is constantly picking up his own flag (i.e. when it continuously respawns on the base polygon).
I highly recommend updating to this version.
