Thanks again for an awesome solution. I installed the 1.19.1 server without issue. I've been running it for a few hours in multiple zones and it seems stable. I am not sure if it's designed for this, but if the toons target is empty, the client doesn't update to clear, it keeps the last known target in the target display. Maybe that's a client thing, or maybe that's how it's supposed to work.
Thanks again!!
