The 190 confusion stems from a detail we overlooked in the skin implemention. Specifically, what happens when we remove a skins and fill that slot with a previously released skin?
Currently, the old skin in that slot is not removed from the 'cache' folder of Aces High II. So, if you have that cached version, you will not get the updated skin. To work around this issue, simply remove the skin from the 'cache' folder and AH will rebuild it on the next access to it.
