Concerning the following comment on Dancing Fever reset when the intermission starts:

Can it go below 60s? Unconfirmed.

I looked through some logs and in the log linked below you can see that the 2nd Dancing Fever went out at 01:05.011 while the 3rd went out at 01:50.193 (so about 15s early). The dance intermission was triggered at 01:06.627 which means the timer can be reset below 60s to the 43-44s timer you usually get when Dancing Fever is delayed by the intermission.

Perfect, I did assume it could so no code change should be needed. We can just update the comment :)

Yep, just wanted to let you know, can pretty much close this immediately 👍
