An very weird thing is happening, when i place items in it, eg. Rune of earth, the sound effect start, but when i target an mana spreader, it does not send the mana to the altar
I've tried to breake everything and replacing but still doesn't work

When i re-enter my world, if the itens are in the altar it works
