UnityEditor.PrefabUtility GetCorrespondingObjectFromSource issue

[coshea]

Hi

I updated TK2d to 2.5.8.9 on Unity 2017.4.40 project and now get this error:

Assets/TK2DROOT/tk2dTileMap/Code/tk2dTileMapBuilderUtil.cs(120,38): error CS0117: `UnityEditor.PrefabUtility' does not contain a definition for `GetCorrespondingObjectFromSource'

I'm actually not using tilemaps at all, I tried deleting the tk2dtilemap folder but then I get a whole bunch of errors for tk2dEditorUtility.cs

Do you know how to fix the above issue?

Thanks
Chris
