I thought Gallery was able to show all of your Google+ albums. Are any of your Google+ albums showing up in Gallery? If not, go to
Settings>Accounts-Google>[your Google email account], and make sure "Google Photos" (
which is different from "Google+ Photos") is checked. Depending on the device or the Android version, it might be "Gallery" or "Picasa" instead "Google Photos."

When you hit the editing screen, does it ask you to "Complete action using," and gives you the choice of the Photo app with "Crop Photo" and the Gallery app with "Crop Picture"? If not, then it's possible at some point that you selected Photos to be the "Always" default app for this last step, and since Photos is buggy when it comes to saving the cropped photo, you're not able to finish the process.
Have you tried Clearing Defaults for Google+ on your Moto G? Try it--go to
Settings>Apps>All, select Google+, and Clear Defaults. Then try the whole process again, always choosing Gallery instead of Photos when given the option.
