[Rseding91] [1.1.61] Reset setting to default is allowed in startup settings whilst map is running

[Xorimuth]

To reproduce:
- Install a mod with a startup setting
- Change it from default
- Load a map
- Open Mod settings > Startup
- Observe that the GUI doesn't allow these settings to be changed, but the individual 'reset setting to default' buttons are still active. Ideally they should be not visibly active but still distinct from the disabled buttons.

If you click on it then the setting is visibly changed, but clicking confirm and re-entering the mod settings interface shows that no changes were actually saved.

Thanks for the report. It's now fixed for the next release.
