Blueprint dissapearing but existing (edit: everything dissapears)

Issue description

I was copying my reactors setup and one line with power generators and pipes just dissapeared but game knows they're there just missing texture. I think it's caused by too many parts copied/cut.

Reproduction steps

I don't know really I have cut them few times to adjust their position and now when I'm happy with that it's just missing textures. Propably you need to make beefy reactor setup and cut it few times.

Game version and build number

Update 3 v0.7.1e (b424)

Operating system

Windows

I've tried to build this setup and everything started to dissapear, please don't tell me my save is dying ;-;

Memory leak bug with large blueprints, it looks like.

We made some improvements, fixed a memory leak, and addressed an issue with misplaced items that occurred during collisions. So hopefully this is now ok. If this happens again, please file a new issue, but make sure to include your save file and the blueprint causing this so we can investigate.
