There is a separate thread on this as well, so be sure to like the other one. My response in that thread...
This needs to be fixed.
I tested this twice and didn't see the skill cap issue. For an interim workaround, if you don't change the ATH position and let the computer place the recruit into the position they're showing with recruiting, it doesn't appear to impose the massive cap changes to the player. Again, only tested this twice with two different players, but I didn't see any ridiculous skill caps after keeping the ATH as an ATH and advancing to the next week. Of course this means the ATH is only going to be able to play at their first assigned position, but at least the skill caps were left untouched.
