Please finish what you're doing error when hopping

[AyKhan24]

The default world hopper plugin allows you to hop worlds with an interface open after your 2nd hop (The first fails with this error and you have to close the interface to hop but subsequent hops do not require closing the interface) but the world finder requires you to close any open interfaces before hopping every time

The full message is:
"Please finish what you're doing before using the World switcher"
