Using the arrow keys to switch tabs in the new-game map generator settings to left/right [basic/resource/terrain/advanced] is broken in several ways:
- Pressing left/right arrow key switches to the next tab on both key_down AND key_up. So one press of a button always moves two tabs in that direction.
- Tab also switches on left_arrow_up when a slider is selected in the advanced tab. So on left_arrow_down the slider is adjusted leftwards and when releasing the key it also switches to terrain tab.
