Cant purchase arcan Isle supporter Pack anymore

I want to purchase the arcane Isle supporter Pack Level 3 today but notized its mit here anymore. Didnt know that a POE1 Update will change the POE 2 supporter Packs. Would be nice if there is a info ingame in that. The other two supporter packs i can buy but my favorite changed, why dont switch this two? Now my futur sorc have no home.
Thanks
