Please check if you can gain exp in magic castle map balefort castle? Pls, Ty

I was farming xp and realized that magic castle map in balefort castle gave more exp than mega mazed. Then suddenly something turn off the exp gain and I can't exp gain anymore in that map! I lost my 2 5-min exp gain elixir!!! I am level 75 aiming 76 and recently spent lots of plats for exp farming (not to brag).. Something smell fishy... Lol
