Astar project and sourcetree

How can i get this to work with source tree? It gives me an error saying ZipEntry not found everytime i redownload the project from bitbucket. I assume it has something to do with the json serialization. But is this project not usable with version control?

change your .gitignore to have this

*.dll
!**/Pathfinding.Ionic.Zip.Reduced.dll

Yes. The dll files are required by the system.
