Clear cache or hard refresh and try again now. Just applied another patch. After talking to some people on discord about the situation I was finally able to reproduce the circumstances where this was happening.
What was it? It looks like a click event that was used on these buttons was not firing, but only if the screen was at a certain resolution. None of my devices were at that resolution which is why I didn't experience it, or most players. I don't yet understand why that would happen, it was the same code from before the update but all libraries were updated, so maybe it had something to do with how they handle click events. Anyway, it was clearly the cause once I was able to reproduce it. I changed it to another type of click event and it seems to be fixed. The reason the original click event was used at all is that it potentially removes a 300ms input delay on older devices, but a delay for some very old devices is a tradeoff worth having to get the button working.
