You where absolutely right! Inserter behind the rocket that i've accidentally spun around.. Now i feel silly..

Thanks for the help though! "Bug" averted

Kinda hard screenshotting things disappearing. How do i upload my save?

Good tip with the inserters! I'll double check. Would be embarrassing/funny if that's the case

I've got a game breaking bug that prevents me from being able to play the expansion.
Whenever i place the Space Platform Starter Pack in the rocket it just disappears. I can't click any buttons to progress and the item is gone and i have to craft a new one. I've tried it multiple times and wasted ...
