What happens to lifetime aspiration rewards if a Uni student changes aspiration?

[cwykes]

What happens to lifetime aspiration rewards if a Uni student changes aspiration?  When the "change aspiration?" dialogue came up, I could see so many possibilities for borkedness that I thought I'd come and ask before I risked it! 

Do you keep the rewards already earned and chosen?
If so, do you end up with an extra 4 rewards?
If not, do you get the points back?

Is the secondary aspiration affected in any way?
Do you get the option to change that as well?
If not, does it stay untouched, get overwritten by the old main aspiration or disappear?
If it goes, do you lose the rewards &/or points?

No.

If not, do you get the points back?

Yes.

Is the secondary aspiration affected in any way?

Secondary aspiration is a reward perk, see above.

If not, does it stay untouched, get overwritten by the old main aspiration or disappear?
If it goes, do you lose the rewards &/or points?

Your points and bar stay as they are, although any perk points allocated are unallocated and must be reallocated. Simple, no pain.

Wow that was quick! 

Do you get ALL the reward points back to reallocate again?  that would be a real "rethink your life" moment!

It's like changing aspiration on the renuyu orb, all your points are set loose again for you to reallocate.
