Recently I delivered an order right before order expiration. The buyer then requests modifications on accident because of the way the new setup is (you can’t type a message to the seller without requesting modifications) and gig is automatically ##LATE##! WTH Fiverr
On a separate but similar topic there used to be an option to make offers for extras onto a gig (for months in 2015), doing this allowed me to extend the deadline, so it was pretty handy when buyers wanted more. Now they REQUEST MODIFICATIONS not knowing that it totally screws the seller over and makes the delivery late automatically.
