something idk what is that

this shows in my console when i join the server:
NOTICE: yield $generator has been deprecated, please use yield from $generator instead.

This isn't a bug ... yet. It's just a warning of PHP that MultiWorld should use ˋyield fromˋ instead of ˋyieldˋ. This will cause a server-crash in future PHP-versions. It should be solved, but it don't have to be solved yet.

Oh ok?
