See, that's the part I don't understand here. Why it's ok to charge (sometimes a lot of) gems on decor, but not ok on stoves? I understand many players just cook to get gems, but if it's a gem stove, it's not like they are losing anything, just do what you do with gem decors, "simply won't buy it and just move on"! Why so much hate and complain?
I do feel for you on buying the stove accidentally though. There should be a confirmation when you spend gems, but we all know it won't happen. THAT to me is an act of greed on S8/TL part
