When can I place a second tile in Rebirth?
Quick answer
You can place a second tile in one turn only by activating the "Place a second Tile" Round Tower Bonus when you occupy a space adjacent to that tower. [p.8 — Place a second Tile]
Details
The "Place a second Tile" ability is a Round Tower Bonus exclusive to the Ireland side of the game. When you place a tile adjacent to one of the four Round Towers with this bonus, you immediately randomly draw one of the four tiles you placed face-down on your Clan Board during setup, then place that tile following all normal placement and scoring rules.

This bonus can only be triggered once per turn. If the second tile you place happens to be adjacent to another "Place a second Tile" Round Tower, you ignore that ability and score only for the tile placement itself—you don't get to place a third tile. [p.8 — Place a second Tile]
Watch out: This ability is only available in the Ireland version of the game (Advanced Mode). The Scotland version has no mechanism for placing multiple tiles in a single turn.
