Need a plugin that disables radiation via permissions and overrides ANY other plugin that's causing radiation.
I have a fixed version of Disable Radiation if you are interested. Feel free to message me here on uMod :)
To add to my message above, I have sent a message to Wulf to potentially become the maintainer of Disable Radiation, so I can upload the fix publically, and maintain it into the future.
Adding one final comment.
I have uploaded the fix for the plugin. Should be good to go now!
