The last months i had always the same setting in the Zone for our Town, and i tested it every new Wipe. But now (since December/January) i experience the Problem that the Patrol Heli attacks, though >NoHeliTargeting< is enabled in /zone flags UI editor. Yeah, it makes no damage, but it shouldn´t attack anyway. Have a look at my UI settings pls.

For some reason the "always on" flag stops working on my server.  Something I have found is when an individual flag stops working, I can re-download the cs file and overwrite the existing. I don't know why that works when there has been no updates,  but it has fixed issues for me when they arise. You might also try reloading the plugin in the console or restarting the server.
