I wanted to host a chatroom event that would last 4320 minutes, but instead of successful event creation, or even a disappointing notice that my event's duration was much too long, all that I have been given is a kitty working on a computer.
I also tried with 2160 minutes and 1440 minutes. This was on chat.stackexchange.com - I wanted to add the event to the GDSE GameJam room, the events title was GDSE GameJam 1.
