Thank you for the response.
I've tried saving my brush presets as a set, as well as resetting preferences but that hasn't really done anything.
The main function Brush Box is for is organizing brushes and while photoshop itself already has a brushes panel, it doesn't have a function for favoriting brushes and putting those in a separate, easy to access folder.
I have a lot of brushes, too many to be honest, but that's mainly because I like to experiment with different ones, and I then save my favorites of the bunch.
Regardless of whether I load them from either the default brush panel or from brushbox the preset will appear in both panels. However, periodically all the brushes listed here in the default panel will dissapear, forcing brushbox to sync to what's in here. When this happens every brush I have favorited dissapears. When I put the brushes back in I have to manually remember and refavorite each of those brushes. It's possible that there is a much simply solution to restoring them but as of now I don't really know of any options. I haven't been able to find any online either, tho perhaps I just haven't looked in the right place? I'm not sure. 
While the brushes are indeed stored here, they don't remain in the actual preset manager, so I have to them reclick and import them.
I'm hoping that I'm just dumb and the solution was simple and in my face the entire time, as I would much prefer that than the scarier alternative that this is just something I'm going to have to live with.
I'm glad that the brushes themselves are still kept as .ABR files, but having to put them back in and look up my favorite one's again has just gotten incredibly demoralizing.
Brushbox is a nice tool, but when introduced it did not like you using both the native Photoshop preset manager and Brushbox. This was before the new system introduced with CC2017 (I think). I wondered if this make Brushbox less relevant, and stopped using it about that time.
I thought I'd look through the user guide before posting this.
Do you have any other brush management systems installed? Brusherator, for instance? 
Yes, the user guide still says not to try using both Photoshop and Brushbox together. I am not
So I think you need to get Derrick involved. He does have an Adobe account, and is always helpful.

Derrick, if you call by this thread, is Brushbox still valid and useful post-CC2017?
thank you for the response, I wasn't aware of those issues 
. I don't have any other 3rd party preset manager's installed, although I do have a 3rd party extension for color (Coolorus) I don't think (I hope at least) that should be an issue though. I don't know if the conflict between the preset manager and brushbox is causing the issue, but thank you for the heads up! Hoping I can figure out this issue soon.
