Odyssey Augments not saving

[CLIENT] Augments are permalocked

I've been having a lot of fun with the new Odyssey game mode, but a huge bug in the client prevents me from saving any changes to my Augment slot(s).

What happens/What I do:

1. Make a change in an augment slot
2. Hit the big "Save"-button
3. See that nothing actually changes
4. Close the augments for the currently selected champion
5. Get a pop-up that asks if you want to save your currently selected augments which shouldn't happen, since you already hit that sweet "Save"-button, but alright
6. Hit "Yes" and switch to another champ's augments
7. Switch back to the original champ's augments
8. See that nothing has changed, since the previously installed augment(s) are still unchanged

This is causing me a lot of trouble since I can't ever replace my augments. It's taking all the fun from Odyssey.

Please fix.

Edit: The whole fuckin client is now incredibly slow and crashing every other second. Hitting "Play" at the top-left only works the first time you ever use it since starting up the client, and the Augment page doesn't even load anymore. This is ridiculous, Riot...
