'Add to Project' deletes all level data

Hello everyone,

I’m creating a project mostly in C++, but I have been editing the world by hitting Debug->Start New Instance in Visual Studios. After saving and creating another instance, everything is right where I left it. Unfortunately, I’ve added a few packs to the project (it doesn’t seem to be any specific pack), and each time I do, it resets the level to the default UE4 state (two chars, a table, etc). Why is this happening and how can I prevent/recover it?

Thanks!

I’m not sure why this is happening to you, would need more details, but it may be resolved if you instead launch the editor from the uproject file such that it runs alongside visual studio rather than being run from visual studio.
