Nope, it's all in the same chunk and yeah, it's Faithful. For some reason the problem went away when I logged in today though. Maybe because of a server restart? Really weird.
today running the latest version i experienced just this, and also correct is a server restart corrects the issue, its as if the server is not aware of the energy sensor cards without the restart, as mentioned if you right click the advanced panel as a client before this restart then it will force the data to be displayed, until the restart any new connection to the server after the panel is placed only shows the counter card stats.
minor issue but none the less as now the server is restarted i can not break it for love or money and that's reassuring
great re work of the mod i must say, many thanks for putting the time and energy to keep this mod alive, i hope the code is not giving you too many headaches!!
Many thanks ben
