Fantasy LCS roster still bugged

Pobelter is both on my roster and listed as an available player. I am unable to drop him (says he isn't on my team) or add him (internal server error).

I had originally drafted him, then dropped him to pick up Febiven (post initial lock). A friend was then able to pick up Pobelter and eventually dropped him. Another friend tried to pick him up and got the internal server error so I dropped Febiven to see if I could pick him back up and drop him (to maybe clear out the bug). I was unable to add Pobelter and cannot add Febiven back (the friend who wants Pobelter is holding Febiven for me for now).
