Description

This PR aims to address a rarer report where clients can sometimes "randomly" disconnect. The working theory is that in rarer circumstances client connections end in a state where their acked flag is not getting reset. This PR removes the reliance on the ack flag entirely and simplifies the resend logic because we now have windowing logic which achieves the same thing.
