CMH TRACON Controller reported a staffing issue which reportedly affected safety of operations for the crew that was working. Controller also reported a UAS had entered the TFR but was delayed in relaying the information.

Narrative

I arrived to work at XA00 for a midnight shift and assigned both North Control and CIC (Controller in Charge). Middletown Sector was staffed with a Controller only; not CIC capable in the Tracon. Prior to me signing on; Management was informed that one of the 4 midnight Controllers would not be in until XC00L. No Controllers or Supervisors were required to be held over to help out with the extraordinary departing traffic or TFR for the event. OSU; a Contract Federal Control Tower stayed open until XE00L; normally closes at XB00L; for the departing traffic. I also informed ZID Columbus sector that I had 35 departures proposed at XC00L and that it would be abnormal traffic for a typical [night]. They thanked me later that I informed them of the extra traffic as they help over extra Controllers to help them work the abnormal traffic. As a CIC; I had a report of a UAS in the TFR and was not able to relay the information to the DEN (Domestic Events Network) until 3 hours after the incident. Management should have been in the facility the entirety of the TFR to help with coordination. 3 Controllers for 3 positions as well as CIC is not a safe operation.
