Clear SharePoint Designer 2013 Cache

 SharePoint Designer 2013 gets confused and acts like an idiot. One way to get it back on track is to reset it’s cache. Here is how,

1. Close SPD2013
2. Delete everything at %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
3. Delete everything at %APPDATA%\Microsoft\Web Server Extensions\Cache
4. Go to SPD2013 options –> General –> Application Options –> Uncheck the “Cache site data across SharePoint Designer sessions”

Relaunch SDP. Easy!
