Currently our setting for megaphones isn't saving correctly when logging off and we have to keep enterting "~setting megaphones disableall". Hopefully this is something that can be fixed, if possible! I did a small bit of testing to find out the specifics. When I had 2 clients open, I used the command on client #1, relogged and it was still working. I restarted the whole client and it was also still working but when I closed both of my clients and started them back up, I had to enter it again on the same character that just previously had it disabled.
Kevin has been notified as of the latest update which sees avatar smega being blocked by the command. Unfortunately he overlooked the fix for it, and will be implementing the fix soon!
