I think it was "You need a source of heat" when I had the powder, but when I didn't, it was "A magical lit candle"
Ohh okay now I understand! The bug is that the description says that the candle is there after you break the drawer but it actually isn't!
What you actually need to do is get the shape of the hand and act on the drawer to put the candle on the table! Otherwise there is no candle there haha.
Sorry about that, I pushed an update that should fix it and make it less confusing. And thanks for helping me find the bug!
