After upgrading to the newest version yesterday I started having some issues...

When I try to edit/create a hotspot, I get this error message:

Fatal error: Call to a member function get() on a non-object in ****/administrator/components/com_hotspots/models/fields/hotspotscategory.php on line 47

All of the hotspots that were previously created are all still there and I can create/edit categories just fine though.

And none of the locations are showing on the map now:

The attached screen shot is what I get when I try to edit a hotspot. Just a white page with that box at the top.

Any ideas?
