Hi,

looks like multiple boundaries were broken in process of editing, can you try correcting them to form polygon again?
List of broken boundaries:
Osun State - https://www.openstreetmap.org/relation/3718720
Irepodun - https://www.openstreetmap.org/relation/3718740
Olorunda - https://www.openstreetmap.org/relation/3718747
Oyo State - https://www.openstreetmap.org/relation/3720554
Surulere - https://www.openstreetmap.org/relation/3720587

Thank you,
David
