Direct link jumps to wrong event

[KatarinaFischer]

When I bookmarked my event (or click on URL on the email invite) it goes to a different event.

I always change then the ID into 31 - But that is the same issue for some users.
Please check.

With Safari on iOS and Mac OS there is an issue when the user wasn't authenticated. When the user is authenticated the link works just fine.
