I'll probably implement the stack thing for hearts and such when they a reach a determined number, I was already thinking about it :) but I won't do the same for the Relics for now
Discount Voucher it's bugged, I just checked; I changed the description but forgot to change the value, so it'll be fixed in the next update!
Yeah probably it's skipping some check when it add Relics via a Consumable effect, will check that.
Thank you!
