one of my blueprints in inventory causes crash on mouseover

[Zuzak]

any attempt to interact with it causes crash.
I cannot into space because a random blueprint I made many hours ago and forgot about is borked.
How do I delete it? / reset inventory fully?

- I suspect it was made when I was messing with train equipment grids and mods. The contents no longer matter to me.
I think this is also the cause of seemingly random crashes when looking at my inventory over the last few days.

Till I figure it out, I'm going to look into some other method without loosing a week of progress.

Problem narrowed down to equipment grid/item issue on a blueprint with locomotive only, no rails. might be roboports in grid.
Disabling my personal mod that slaps an equipment grid on trains allowed me to delete the problem blueprints.
Modded my mod to avoid train grids for now. Might be better to just have spiders that follow train. Could get more total inventory space too. Spider parade.

Now on to space!
