Each time I attempt to access the sprite editor I keep getting this message:
SpriteCollection 'GuiSprites' - Upgraded from version 3
UnityEngine.Debug:Log(Object)
tk2dSpriteCollection:Upgrade() (at Assets/TK2DROOT/tk2d/Code/Sprites/tk2dSpriteCollection.cs:613)
tk2dEditor.SpriteCollectionEditor.SpriteCollectionProxy:CopyFromSource() (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteCollectionEditor/tk2dSpriteCollectionEditorProxy.cs:22)
tk2dEditor.SpriteCollectionEditor.SpriteCollectionProxy:.ctor(tk2dSpriteCollection) (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteCollectionEditor/tk2dSpriteCollectionEditorProxy.cs:17)
tk2dSpriteCollectionEditorPopup:SetGenerator(tk2dSpriteCollection) (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteCollectionEditor/tk2dSpriteCollectionEditorPopup.cs:234)
tk2dSpriteCollectionEditor:OnInspectorGUI() (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteCollectionEditor/tk2dSpriteCollectionEditor.cs:61)
UnityEditor.DockArea:OnGUI()
I can't edit the sprite sets now, which is a bad thing! Even creating a new set exhibits the same issue.
For the record, I've reinstalled the tk2d package as well, and that didn't fix it, either. My entire project is in C#, if that is useful to know.
Any help very much appreciated.
