While making game #29058645 on frankfurt, on google chrome Version 75.0.3770.142 (Official Build) (64-bit), I was unable to select the option for 0-4 or 0-3 event/landmark/projects. As you can see from the screenshot I have uploaded, I could not checkmark the black box that would allow for "none" to be an option. Typically, I will add all 4 slots to be filled by all or nothing, but now when I click on the black box it just unchecks one of the event, landmark, or project options. Looks like that slot is broken.
