Thanks for the update!
Many warnings fixed, but I am getting this one:
Invalid AssetDatabase path: C:/Program Files/Unity/Editor/Data/UnityExtensions/Unity/VR/Android/unitygvr.aar. Use path relative to the project folder.
UnityEditor.AssetDatabase:AssetPathToGUID(String)
tk2dSpriteCollectionBuilder:RebuildOutOfDate(String[]) (at Assets/TK2DROOT/tk2d/Editor/Sprites/tk2dSpriteCollectionBuilder.cs:164)
tk2dSpriteCollectionTextureWatcher:OnPostprocessAllAssets(String[], String[], String[], String[]) (at Assets/TK2DROOT/tk2d/Editor/Sprites/tk2dSpriteCollectionTextureWatcher.cs:24)
UnityEditor.AssetPostprocessingInternal:PostprocessAllAssets(String[], String[], String[], String[], String[])
Looks like this is only 1 warning, but it appears about 1000 times if I rebuild the entire project
Not sure if this can be a problem or I can just ignore it.
Thanks!
EDIT: I am using 2.5.8.2 and Unity 2017.1.0f3
