Able to find session when there is none to find?

Hello, I’m trying a simple blueprint session multiplayer game. And something really weird just happened. I’m able to find session when there is none to be found…

So the case is no one is hosting a game, and I’m searching on LAN.

Blueprint:

From log:

[2017.01.19-04.04.27:438][367]LogBlueprintUserMessages: [WaitLevel_C_0] Session found. Server name:
[2017.01.19-04.04.27:438][367]LogBlueprintUserMessages: [WaitLevel_C_0] Error: can’t join session!

I’ll edit it to check if the array is empty before joining but still…
