Glommer does not appear

I was playing with some friends and we killed glommer right on nightfall (a last minute decision in order to spawn Krampus). I ran down to his statue and saw the flower there - I picked it and he didnt show up and it still looked as though the flower was on the statue (only I couldnt pick it more than once).

I destroyed his original flower, but still have the flower that I picked off the statue as it is not rotting. There is no Glommer in the world. Now on fullmoons - nothing appears on the statue - as though he around and alive.

Any ideas what I can do to fix this?
