Good morning,
Following your post, I can confirm that there’s currently two contradicting issues:
- The quest Ogre Waygates does say that “we can build a one-way portal from your garrison to that location”.
- The ogre waygates have been two-way in the past, and seem to be one-way only since the patch.
As to which one is actually intended by the developers, we (customer support) don’t know that at the moment, however I can say that they’re now aware of this issue (i.e. they’ll be the ones deciding if the waygates are supposed to be one-way, or should allow players to return to their garrison).
Thanks for the information posted so far, and hopefully this can get resolved soon!
