I'm using Unity 5.2.3f1
2dtoolkit version 2.5.4
When I run a scene in the Editor, everything display correctly. If I load a scene from AssetBundle that contains GameObject that are tk2dsprites, all of them becomes pink color, the tk2dsprite collection show as "-" .
I created a simple scene to investigate this issue. Two attachments were included,
First one display a gear icon correctly if running the scene in Editor, or build into the main app, without using asset bundle.
the Second one display the gear icon in pink, if this scene is loaded from an Asset Bundle.
I have verified the asset bundle codes should be correct, as all other things loaded properly, it's just issue with tk2d related game object.
Hope to get some ideas. Regards..
