General slowness with 3.7.9.RC6 with clients/host

Please be as detailed as possible (general things you might want to include in your post);
what you are trying to do exactly?
Host a game with imported tokens from previous 3.7.8.
Clean install, imported all maps, and tokens
Everything was running fine until clients connected, it slowed down. Even typing in chat was progressively slow and even doing chats within the character tokens.

what the result was and/or what steps you took?
I closed out the session and opened it without the batch file - same result
I had 4 gigs of RAM, up'ed it to 6 gigs of RAM, same thing
Closed and rebooted my computer - same results
I rebooted my PC and had the clients reconnect - same thing

When I was on version 3.7.8 beta 4, we didn't experience any of the slowness that we did in this new version.

Is the issue repeatable?
Yes, during the whole session

Windows 10.0.18362
