After updating atavism from 10.5 to 10.8 cannot get past CharacterSelectionScene

[InfinityRealms]

I have update atavism iteratively from 10.5 to 10.8 following wiki guide. Haven't tested versions in between, so just updated step by step to 10.8 and started testing. In atavism we have custom initial authorization which get you through the login scene by hooking up account on our website with game. We did some custom coding but everything worked in 10.5. After i have updated to 10.8 i have added those files, and our authorization works, i can get to CharacterSelectionScene but cannot get past that(in other words pressing `Enter` just returns me to login scene after 10 seconds. In ubuntu terminal i get this error:
 
In logs file i've found error in prefab_manager:

It would be good if you could send all packed logs in private, preferably at debug level.

It was caused by mixed settings of TCP/UDP between the server and the client.
