I can't find anything on this.

It might be me being stupid.

I'm level 21

I enter the battle, Miraak starts talking, I attack him anyways because I don't give a crap about the arrogant bastard and I just want to reset my perks, get out of there, and tame dragons.

The rest of the questline was glitch-free and super fun.

I get him down quite a bit (I don't think 30%? Sorry, I'm not sure) he poofs away and dragons start flying around.

Now what...?

I've been sitting here and waiting forever.

Killed a dragon. He isn't reappearing.

At this point, I'm so frustrated I kinda just want to console kill him and leave and get outta there.

But where the hell is he? He just isn't reappearing.

Is there something I'm supposed to do?

This battle is known to be extremely buggy. The best way to solve this would be reload a save prior to starting the battle (or before riding the dragon to the summit of Apocrypha). Sometimes if you try to rush through the battle too quickly it can become bugged. If you are able to revert to a previous save, try not to rush the battle next time and see if it makes a difference.

Also, if you don't use the http://afkmods.iguanadons.net/index.php?/files/category/95-unofficial-patch-project/ already, try using those. The Unofficial Dragonborn Patch fixes several bugs related to this battle; it "may" solve the issue you are having if you end up reloading a previous save.

Ok thanks I'll try that and see if anything changes c:

It's going ok now.

The son of a [censored] is hard though.
