Character falling by (Destructible) Actor through landscape

Hi, I have a destructible actor that has ho physics simulation.
At some point I enable the physics through bp.
Then, if I step on this actor with my character, the caracter falls through the landscape about 400 units. If I step aside the character gets back on a “normal” position.
But it seems not to has to do with collision/physics settings. If I play not over network (dedicatet off / 1 player) everything is like it shoud. The character steps on the actor. This only appears if I simulate network. If I am the listen server its a bit different. The character does not fall through the landscape but it shakes.

Both, character and actor have replication and replicate movement enabled.
I think I have every replication settings testet but nothing helps.

What I also figured out is, if I am in Multiplayer/Network game and start with simulate physics true on the destructible actor also everything is fine. The problem is when I start with no physics and enable physics during play. I think it is a bug, isn’t it?

Ok, now I found the issue. I have not replicated two vars. With replication the problem is fixed.
