If you’re one of the lucky ones who drops from the TFAR channel and then rejoins every time you use the Arsenal in various ways (typically the Loadout Selection in ace arsenal for me) I have a workaround!
In game, Press Escape, Select Options->Addon Options->TFAR Clientside Settings->Plugin Timeout in Seconds
I’ve set mine to 9.0 and it seems to work.
