[POE 2] Unable to return to Aggorat after completing Act 3 boss

Any update on this in 0.3 Rise of the Abyssal season? I defeated the Act 3 boss with the Sacrificial Heart still in my inventory and the time gateway has now closed.

Am I screwed?

Answering my own question. No I am not screwed. I did this:

1: Fast travel to the Act 1 Clearfell Emcampment.
2: Log out and back in.
3: Fast travel to Act 3 Ziggurat Encampment. I arrived with the gateway still open!
4: Go through gateway to go back in time.
5: Fast travel to Aggorat and find the altar.
