[2.1.11] peaceful mode does not trigger warning when starting game

[miege1000]

The tooltip of peaceful mode in the new game settings says that it will disable some achievements, however when it is checked and you start a new game, the usual warning dialog with the disabled achievements and the reasoning does not show up and the game immediately starts.

Also, instead of a huge wall of text for the disabled achievements, the UI could be hugely improved by adding a list of icons instead

Thanks for the report. This is now fixed for the next release.
