Wrath Of The Lamb 1.48Edit

[BUGS] (add onto if you find any)

• For some, the unlockables "Cain's Eye", "Eve's Bird Foot", "Samson's Lock" and "The Left Hand" do not properly save and are lost when the game exits. Upon restart, the stats page will show 93/97, making Platinum God impossible to achieve. This happens on Mac OS and Windows.
• Killing War's horse with a poison while he is in the air throwing bombs will leave him there, making you unable to finish the match.

• Making a deal with the devil to remove your last heart while you have soul hearts will remove the soul hearts aswell. When this occurs your life becomes -1 and you must aquire 2 health ups before you gain a red heart, after that you gain health as normal. \\ This is not accurate from my experience. If one spends all of one's normal hearts in a deal with the devil WITHOUT exceeding one's total normal hearts, the soul hearts will remain. Unknown if this is a bug or intentional - the excess heart taken effectively puts you in "debt" with the devil.
• Numerous Familiars clashing with each other. For example picking up Holy Water while nearly any given familiar is equipped, will turn it into Brother Bobby.
• Completing the Chest using Eve unlocks "???'s Soul" instead of "Eve's Bird Foot"
• Sometimes when fighting Conquest in the Depths/Necropolis, in the "Isaac vs Boss" screen it will show War instead of Conquest.
• The "3 Dollar Bill" will sometimes add the effect of "Magnet" instead of a tear effect
• If you get killed by one of Peep's eyes, it'll say that a fly killed you.
