I think that T. Forgotten has a damage up of some kind applied to the pile of bone toss landing a direct hit? It's weird and I guarantee unintentional

Also, black hearts look like they just have a frame of the character holding up the necronomicon, which may/may not be an issue from this mod as well

Also, the encyclopedia thing for the birthcake doesn't work, there is no info, won't let me check its stats, etc.

I don't think the black heart thing come from this mod. As for T Forgotten, i don't seem to reproduce the effect in anyway and i think as how the code is working, it can't really change the bone damage
As for the encyclopedia, i haven't done it yet :D

while playing T isaac EID says "BIRTHCAKE_DESCRIPTION"

I ran into an extremely strange minor text bug. While playing as Eevee, from the Eevee mod, I picked up Midas Touch, and for some reason, the pick-up text read "EEVEE'S CAKE". Given that this matches the name format of this mod, I assume that the two are related?

Noticed an issue that can cause some active item-related effects in other mods to break (such as some in Fiend Folio & others)

There are some lines in the code that "return false" in the MC_PRE_USE_ITEM callback - despite having no immediate effect, returning non-nil will skip the MC_PRE_USE_ITEM callbacks (& code) of all mods that run after yours.

Basically you just need to change "return false" to either "return" or "return nil" (theres no difference) in the following places (as of the current patch):

isaac.lua, lines 97 & 119
jacob.lua, line 123
magdelene.lua, line 28
thelost.lua, line 24

Would be greatly appreciated if this could be fixed. Thanks!

Found a bug playing as Tainted Bethany. Maybe its because of something I downloaded I'm not sure, but I used Lemegeton in a Curse Room and the trinket wasn't consumed. Not only that but my blood charges didn't decrease, the book never lost any charges, and I could just print wisps until I maxed it out. It didn't matter which room I was in either, as long as I held onto the trinket I had infinite wisps. While it was funny I felt like I should mention this

while playing as T. azazel EID says "BIRTHCAKE_DESCRIPTION"

also T Azazel has a weird interaction with Ludovico,trying to move the ring will sent Azazel flying in te opposite direction you are trying to move, which is weird when you can't sneeze with ludo.

I don't know if this also happens with other tear modifiers on T. Azazel.

while playing Normal Eden. Picking up an item that the birthcake WOULD GIVE (even if you don't have the trinket) will remove said item.

example: was playing eden, picked up birthcake, got tarot cloth, later dropped birthcake. picked up tarot cloth in a shop later on, buying the tarot cloth did not give me the item at all.

This mod breaks Fiend Folio, The Deleted, The Stranger, and probably others. Golem's subway button doesn't show up, Deleted's character switcher doesn't work, and Stranger straight up breaks entirely. I have no idea why this is the case but something is very broken here.

Magdalene's cake replaces hearts when exiting and re-entering rooms. That way you can always get double red hearts.

I got the same bug as a previous person but its universal, EVERYONE'S birthcake name and description appears over what would be the name and description for midas touch, its for every character, if im playing as issac it shows issac's, if im playing tainted keeper it shows his and so on so forth

Using the "Clicker" item as Jacob and Esau when birthcake is in the room or held crashes the game.

When using blue baby birthcake, combined with glass canon and 9 volt, hunderds of poops spawn, an you can spam it. Reaching the max of entities in only 2 clicks of the space bar.

Cycle chance is always set to .25 after restarting the game, even after changing it

Found weird glitch. If both Jacob and Esau have rock bottom and different stats, after picking up, dropping and picking up again as other brother, stats going higher. What's weirder, they not just going infinetly higher, boost progressively getting smaller
