Thank You! Experimental it is
Also, thanks for such a quick response. Love the game, You guys are the best.

My original blueprint storage is here, if it helps...
Thank You!

I have a very similar issue, I'm also unable to launch my Space age game.
When I try to launch game from map generator, I get a notice about failing to copy blueprint-storage-2.dat and this file seems to be entirely missing in my folder.
