Can't get zone radius lower than 100Solved

I've changed the data file for my small arena  "Zone Radius": "40", and save but when I reload the plugin it reverts back to 100 is there something I'm doing wrong?

Update: I have also added a zone to the area and the raidus is set for 40 as well

Is it a custom event? You need to unload the plugin before you can modify the data file....
You know its the simplist of things that make me feel dumb lol... Thankyou
