Crash when importing Texture2D Sprite Atlas

[Fuley-la-joo]

"There Is No Game: Wrong Dimension" has most of its Sprites packed into Texture2D images, but when trying to replace these in UABE 3.0, the program simply closes without any errors appearing. This doesn't happen with Texture2Ds that aren't used as Sprites or Texture2Ds where the whole image is used as a single Sprite. The game also uses IL2CPP if that's relevant.
