Email Filters broken

Email Filters broken

Anyone had issues saving a new or editing and saving an existing email filter with a Forward To?
Every time i try in safari or chrome the AJAX on save bums out with a required script hitting a 500 HTTP response. so it doesn't save. Only seems to happen when trying to use the forward to option field in the mail filter rule.

PS: tried submitting support tickets several times but not heard back, and can't check on status because help.zoho.com seems to use a completely different authentication source...
