Lightroom CC adjustment brush changing size on its own

[seanm60824241]

I'm having a frequent issue where the size my adjustment brush in Lightroom CC will change on its own mid-edit -- which is really frustrating having to go back and readjust repeatedly with each photo. Anyone know a way I can fix this, or is it a bug and I just have to wait for a new update that corrects it?
