I believe this is a bug with Tiberian Dawn, not Blueprint Sandboxes. A quick peek reveals that it does not handle on_force_created, therefore when this mod creates a new Force and adds Research to it, Tiberian Dawn attempts to store some meta-data for that Research into its own storage for Forces - which is missing this new Force - it crashes as you've shown.

I've opened a bug-report on their mod-page.

thanks！
