Ok, so after spending way too long crawling through the thread, turns out someone else had run into this issue before, and was told that the settings were no longer part of the toolbar button's menu (as the wiki and in-game messages still claim), but rather in the difficulty settings you have to change when creating a new game. Meaning they can't be changed while playing an already started game. Fortunately, I did manage to locate the settings file for my saved game, and after some fiddling was able to change things to my liking. I would like to suggest to Angel that he should probably change the in-game messages and the wiki to reflect that the in-game settings menu is no longer there, and that you need to make changes before starting a game. Would probably help prevent confusion for anyone else.
