Client - Game Tick increases over time and renders game unplayable

Hey all,
i have a local lan multiplayer setup for a vr app.

Somehow on my client the game time (from stat unit) starts to raise and raise and also increases the fps ms so fast that the game renders unusable. I establish connection via sessions.

Where can i start to look into this problem? What kind of errors can cause this?
There are no visible errors in the console/log files. I connected via editor into the game for debuging and there are no actors that pile up. Really nothing that i understand there.

I’m using protheus mp template that works fine in all other cases. I attached the log files. Log1Log

It was the missing/bad garbage collection. Splines, Splinemeshes and other things you spawn in blueprints should be checked. It got replicated but not destroyed resulting in endless hidden meshes and objects. Its always the same with splines / 3d widgets and other things.
