Its a design flaw and they had no intention to change it when reported

had an errata in UpdateJuly2012.
Pg. 02 The Mariner Sea Legs Power can be triggered off of its effect successively in chain until successful and therefore should have a Special line saying ''Special: You can use this power only once per turn'' to limit its use.
Pg. 05 Unearthed Arcana: Using Ships In Your Campaign is missing the word ''DM'' in the sentence: ''The determines whether an item is appropriate for a particular kind of ship.''
Pg. 03 Channel Divinity: Chauntea and Silvanus's Forest Father's Grasp Power is missing a Target line.
Pg. 05 Channel Divinity: Chauntea and Silvanus's Nature's Fervor Divine Boon does not scale whatsoever and thus gains nothing from higher levels. The Level 28 boon is identical to the Level 3 one.
