...s/game data/Krastorio/temp/currently-playing/control.lua:67: in function <...s/game data/Krastorio/temp/currently-playing/control.lua:30>

Super easy to repro:
1. get Edit-Blueprints and Braver_New_World
2. Start the Braver Scenario
3. Copy anything
4. Click the 'E' Button with the blueprint
5. Try to use Q to select anything in the blueprint.

Save here (Already has the blueprint open, just press Q on something): https://drive.google.com/file/d/1b9tA1VN2I_-ZWwBy6lPye4jkxSm9AT6o/view?usp=sharing
