For anyone who try to reach act 3 past map

[postgresql5432]

after you finish last boss in act 3 game gonna tell you to go to cruel difficulty but if you still have something to do at last 3 map of act 3 like heart side quest / farming gear.

just use gateway (same portal that will send you to past version of town and to cruel difficulty after you killing last boss) it will switch between act past and present map

To Dev : it might be good if act 3 map have 2 version on tab at world map screen so we don't have to teleport to riverbank every time we doing this or go through gateway every time to access stash.
