This be the smallest of bugs I’ve ever to report, but if you go to MessagingService on wiki it will look like this:
So you need atleast 6 players to get to do one subscribtion (-5 + 2 x 3 = 1)?
It’s clear from the above limitations that they are using ‘-’ as a bullet marker.
It really confused me at first cause all I read was the Subscription limitations.
I’d suggest using real bullet markers.
