[Editor] Fatal error on openning

Hi.

I have a project made on windows. I zip it and unzip it on MACOS. When I open the project on the mac, I get the error:

“FatalError, m_PathToGUID.erase (aGood) !=1”

Unity version on windows ==> 5.5.1f1
Unity version on mac ==> 5.5.0f3

Remark ==> I know openning a project on a different version of Unity is not supported, but it worked very well until now.
