I'd like the expand on another method of reproduction,

I experienced this while hosting a save

• I pasted a blueprint while still in sandbox mod (mod link in the first message)
• opened an configured LTN Combinator from the blueprint
• removed the requested item
• Opened FNEI
• Save crashed.

Note: Removing the ltn stations from the blueprint, allows the save to continue, while doing the steps above.
