@Jimbohalo10 We’ve done a 3/4 day debug session and posted the results here: [[CRITICAL] Tycoon Unjoinable “Network Connection Lost” After 15min – Matchmaking Still Sends Players - #8 by thrax207](https://forums.unrealengine.com/t/critical-tycoon-unjoinable-network-connection-lost-after-15min-matchmaking-still-sends-players/2562223/8)

Do you see any logic? I can’t make to seem any sense off it.  
It appears the more of my verse code I disable, the **later** the bug appears, but it will eventually appear?

We’re going to now debug this map code you shared here with 5 accounts, we’ll let you know any outcomes.
