Build 26301329

Two patches within 48 hours! There were some annoying bugs that were fixed yesterday and today, so I figured another release couldn't hurt.

- (Negative) Scenario effects are now displayed at the start of a scenario in the rules for that scenario.
- Fixed black screen plaguing some people when exiting the game at the loss screen.
- Going back to town and undoing are now more reliable in error popups.
- Fixed prosperity gold for new characters.
- Fixed some item issues.
