When creating a blueprint or using the copy function, hovering over the structure you want to copy, and then, without finalizing the blueprint, pressing 1, 2, or any other hotkey to select an item makes my game crash immediatly.
I would expect it to cancel the blueprint and put whatever item I attempted to select on my cursor.
To reproduce, create a new blueprint or use the copy function, select any amount of placeable structures, then use a hotkey related to the hotbar. Happens to me 100% of the time. This can be reproduced on any new save within seconds without fail by placing down the starting furnace and attempting to copy that. The hotbar slot doesn't need to have an item specified in order to cause the crash.
While initially discovered with mods in use, it still occurs without any turned on.

I have the same/similar issue with the game instant crashing related to Blueprints. I can get it to reproduce by simply clicking on a blueprint book from the hotbar and moving the mouse over to the game field. Game crashes every time. I was attempting to make a book in a book and had the blueprint window open. Did the same thing with no blueprint window open, still crashed. I tried a 3rd time by moveing the blueprint window over part of the hotbar then moved the new-unnamed blueprint book from the hotbar to the blueprint window and there was no crash, I was able to place the book...

I'm running Krastorio 2 and FNEI, everything up to date.

I've added my dump log file.

Thanks for the report, resolved in 0.18.42.
