Dying Light 2 Story DLC Delayed

Techland tweets that the planned first story DLC for Dying Light 2: Stay Human is being delayed. We're now told to expect new content for the zombie sequel in September. Something, something feedback:
Dear Pilgrims, your feedback always has the highest priority for us, and we want to be honest and transparent with you. We will still need a bit more time to develop the first story DLC. It is now planned to be released in September.
