I've split this topic from the known interface issue, because it is IMO not as clear cut as the other topics brought up (Thanks, JW!. I would have sworn there are already 1000 posts about the moving reveal window, but then I couldn't find any).
What I fail to see is what in this situation is so special. Sometimes the UI comes in the form of buttons, like Watchtower. Sometimes it comes in the form of clickable entries in the log area, like for a trashed Feodum or Fortress. Sometimes it comes in the form of Reactions clickable in your hand ,e.g. Market Square.
That means that in some situations, when more than one effect triggers, more than one method may apply (which can be confusing, no doubt). If you don't know about the clickable entry in the log area, you will be confused when something appears there, because the game apparently doesn't move forward.
If I understand you correctly, you argue (based on the post in f.ds) that the presence of the 2 buttons from Watchtower is so 'big' that people fail to take into account that another option is presented to them in the log area. Is that right?
