after last night's update - old campaign links don't work

[nadworks]

It seems links from campaigns sent yesterday have now stopped working (today), coming up with the error:
strpos(): Argument #1 ($haystack) must be of type string, int given
... when clicked on from within the campaign.

Several clients sending me panic messages. Any help? Can I roll back?

This is fixed in the latest update we made available one hour ago, v2.2.16.
We're sorry for any inconvenience this has caused
