Cant teleport to Act 3 from Act 4

It is impossible for me to TP back in Act 3 (modern time)
It only allows to teleport to 400 BC timeline. However when i pass through the time gates I teleport to Act 4 start location, and teleports are disabled there I have to clear the map and boss just to reach closest teleport gates.
What should I do if I need to trade with player in Act 3 / play with my friend/ complete some quests / finish 2'nd Ascendancy Trial ?

Hey, I got the same bug. It's game breaking to honest. Did you find a way to go around it and get back to proper act 3?

EDIT:
Fixed after I finished act 1 on cruel...
