• Added a couple new abandoned planetarium layouts.
  
• Fixed an error that could occur in one of the special layouts.

• Fixed item layouts still spawning a zodiac item even when you have Chaos.

Other updates/fixes:

• Add 2 super secret rooms that contain a Wisp Wizard (weight of both rooms is halved, so in total they have 1 weight instead of 2). If you don't have them unlocked there'll be a key beggar instead.

  end

Tweaked the amount of charges that certain pickups/consumables add to Singularity:

• Golden keys/bombs: 2 -> 3
  
• Charged keys: 6 -> 4
  
• Void/Abyss/Similar synergies: 4 -> 6
  
• 48 Hour Energy: 6 -> 2
  
• Horse 48 Hour Energy: 12 -> 4

• T Andromeda is now able to get the Spode transformation before it's unlocked.

• Fixed Alpha Centauri not being able to turn chests into wisps.
  
• Fixed frozen enemies triggering on death effects of certain items.

• HP ups for T Andromeda are now converted into black hearts instead of soul hearts, similar to T Judas.
  
• Fixed T Andromeda taking unfair damage from certain rooms where tnt explodes instantly.

Oh boy here we go, the first nerf to T Andromeda. Now before you lose your mind, take a second to read my explanation for it.

• Deal rooms no longer stay open for T Andromeda when re-entering the boss room.

If you had something like Goat Head, you could just go straight to the boss and clear the rest of the floor to spam Singularity in there. With this change you can't really do that anymore. However, there still aren't any restrictions when it comes to using Singularity to spawn items in devil/angel rooms. You can already get 2 items per deal room if you play it right. This also doesn't affect other ways of teleporting into deal rooms such as Joker cards. On top of that, it doesn't lower the overall amount of items you'd get. It just means you need to use Singularity elsewhere. I didn't want to make more restrictions for certain rooms so I felt that this was the best way to do it.
Let's be real, there's still plenty of ways to break the character even with this change.

• Reduced the spawn rate of Spode tears from tech lasers.
  
• Increased the damage gained per room from Pallas.
  
• Added a synergy between Book of Cosmos and Crying Pebble.
  
• Using Ancient Recall no longer adds a charge to Singularity.
  
• Fixed the mod making the achievement paper blue (oops).

• The abandoned planetarium now has its own unique song! Special thanks to Nihil for making it! The song is titled "Gazing At the Edge of the Universe"
  
• Items from boss rooms on the void are no longer removed for T Andromeda.
  
• When Singularity spawns an item for other characters, it now pulls from a random pool instead of the current room's pool.
  
• Updated some Russian EID descriptions.

• Tears from Spode can no longer turn into Trisagion tears.
  
• 10% of the damage gained from exploring rooms with Pallas becomes permanent when moving to the next floor.
  
• Juno now gives a soul heart on pickup.
  
• Fixed Vesta's flames being able to break your holy mantle shield.
  
• Fixed a bug that prevented you from being able to open the mausoleum door when you have Chiron.

• Tweaked several item sprites.
  
• Added "outline" for T Andromeda's look (probably nor forever).
