When setting a defense team with fewer than five heroes, the team presentation for players attempting to raid it does not reflect the hero positioning in the team editing menu (below, image 1).
The intent of leaving gaps in the defense is to force an unknown for the middle position; because the display centers the heroes on the defense during offense team selection, it is not possible to tell which is in the middle position (in this case, Kunchen or Guinevere), which creates potential color mismatches (below, image 2).
The issue is that the vacant position is not actually ordered correctly in the defense as players encounter it (below, image 3). From the original defense specified in the edit screen, Alberich should occupy the second position from the left, not the far left position. At a guess, the issue is that team order is filled from left to right, not accounting for deliberate gaps elsewhere.
I realize this is a relatively minor issue, however it is still important to consider for deeper strategy and defense development. Please let me know if you have any questions regarding either the strategy or the positioning issues, and I’ll try my best to reproduce it.
