Randomly leaving build mode and random loading when roaming

[astor]

My Google-Fu is weak.  

 

I cannot find how to fix my issues:

 

1.  When i'm in build mode in any settlement, build mode keeps cancelling.  It's not game breaking, but it's very annoying and has only started since the 1.7.15 patch.

 

2. When i'm out, roaming the wasteland, or in the city area (doesn't matter), i keep getting random loading.  The game freezes, the loading icon pops in the bottom right, and i have to wait for 30 or longer to resume my travels.    

 

 

Help?
