My passive skill tree is glitching. Can not take keystone.

I worked my way to the mind over matter keystone. Something weird happened where the connecting lines were not appearing but the nodes were activating. When I got to the keystone it would not let me activate it. I had to make sure that I was right so I checked and I could refund the passive right next to the keystone. I did try refunding it and reactivating it but it still would not let me get the keystone.

Game breaking.
