2D Extras Error

Hi,
I have recently downloaded a 2D extras kit from here: Unity 2D Extras
I imported this into my project without any problems, but upon importing I received an error, and the toolbar was not updated. Here is the error:
Assets\Tilemap\Tiles\Rule Tile\Scripts\Editor\CustomRuleTileMenu.cs(8,31): error CS0117: ‘ProjectWindowUtil’ does not contain a definition for ‘CreateScriptAssetFromTemplateFile’

Any ideas?

@YuBen
Same problem here.

Same, I also had issues with the GameObject brush

Not the ideal option, but here is the link to the techdemo of these brushes. This was able to import fine to my project.

I have a similar issue. kiss anime
