How do I safely switch layouts when using the Multiplayer plugin?

Hi,

I'm making a multiplayer game (using Construct's Multiplayer plugin) and the engine seems to freak out about destroying synced objects when I try to switch layouts. My guess is that basically if they are not switched exactly at the same time, the engine has a hard time keeping the same amount of sync objects created on host and peers. What is the intended way of changing layouts for Multiplayer plugin games?

Thanks!
