While checking the wiki, we found a few magic items whose descriptions promised more than they gave. The descriptions now tell the truth:

• Reindeer: pays 1,000 coins per level each night (the old text said 3,000).
• Fire charger: gives 2.5% (the old text said 3%).
• Ho Ho Horse: each night, all your horses that aren't retired gain 10 happiness, however many Ho Ho Horses you own.

What the items do has not changed, only the wording.

The ads disabling potion is no longer sold: the game no longer shows the old ad bar, so it had nothing left to do. If you already have one, it stays in your items.
