Example Project vs 2D Extras

After installing the 2D Extras package from https://github.com/Unity-Technologies/2d-extras into the Lost Crypt example project I get this barrage of errors. I don't know where to start in order to fixing them.

Might not work, but the first thing I'd try is to exit out of everything, delete your Library/Temp folders in your project to force a re-import when opening the project back up. That can sometimes solve errors. The second thing I would suspect is perhaps either Lost Crypt or the 2D Extras is out of date. Third, perhaps they have some incompatibility they forgot to address. These packages should be compatible though.
