@Savage One thing you have to keep in mind is that the bid is an input field and therefore changeable. If I remember correctly the only thing the 5% does is just add a standard value to the input field, which is 5% higher. So if there's a card for 100 current bid then the enter bid field will be 105 but you can change it to 101 and bid 101.

Looks like you missed a tower  @Savage
 

This seems to be very unlucky map generation. The tower was generated just outside the playable area of the map. This would explain why your construct/giant wyrms didn't attack it.
