Tilliboy or other team members might ask you to attach a couple of saves in a zip file. One will be game with ess extension & the other with SKSE extenion.
default path: Documents > My Games > Skyrim > saves
Safest things to try if haven't done so.
Reboot, load game again and exit area-- take a myrad flight somewhere, etc. Return & see if game has 'caught up.'
If not, following console may or not 'jog' the dialogue & get things rolling again

Should move Calia to your location. Sometimes that's helped me proceed with dialogue, other times no...
Anyway, hope that helps!
