[2.0.27][demo] Error in background simulations

[eugenekay]

What did you do?
- Installed Factorio Experimental (v2.0.31, via Steam)
- Installed the Factorio Demo (v2.0.27, Build 81069)
- Renamed %appdata%/Factorio/ to %appdata%/zactorio (to eliminate effects from Mods, Saves, Settings, etc from the Steam version)
- Started the Demo
- Waited for the Menu Simulation to change

What did you expect to happen instead? It might be obvious to you, but do it anyway!
Main Menu Simulations would play in background endlessly.

Does it happen always, once, or sometimes?
Sometimes, when the Menu Simulation Changes. It also happens sometimes when "Exit"-ing to Main Menu.
