The bugged trophy is: The impregnated one.

I've been stuck at 14/15 for quite some time now. I even did 3/4 of the last events and still nothing. That trophy gives 8000 crystals and could be a follow up trophy afterwards which could reward even more which I've now missed 2 out of (counting the one from 15).

No idea how to get it fixed or anything but please take a look at it.

Trophies from act 10 are probably not taken in account.
It's indeed a bug.

Alright, is there anything that could fix it?

Yes, the staff on Monday....
