I have been working on a custom scenario for over 30 hours now, But I have for a while now been unable to test it.
Yesterday, when I tried testing it (and playing it in a multiplayer lobby) I would get kicked back to the main menu: “File Error 23”
Today when I tried testing it, It worked the first time, But since then, Every time I try the game crashes.
I should probably mention that the game created a copy of my scenario called “default0” that has got its own separate (but identical) file in my folder. It also mirrors all the updates I make to my original scenario, and keeps itself updated. I don’t know why this exists, and if I should delete it.
