Network blackscreen

Hello.

So whenever i set number of players to 2 i get black screen on second client, and engine freezes as well. Tried launching separately, via “ue4editor PathToProject.uproject /Game/Maps/Map?listen -server” and connecting via cmd as well.

Once loaded i see map for a second and then it becomes black, console is active though.

One of latest log entries:

I’ve had problem similar to this, when engine was crashing on networked PIE as soon as i use custom HUD actor in the game mode. Current project was working at first, i’m totally not sure after which code changes it started to happen.

I’ve seen other questions about black screen, but they’re useless as i don’t have that bigfoot card.

Thanks in advance.

Bump, it got burrowed pretty deep

Was able to launch it, once i deleted all the code in character’s tick function.

Edit: traced to the problematic line, it’s the following:

APlayerController* PlayerController = CastChecked<AGameCharacter>(GetController());
