So anyone a idea why my players reset, after i edit them? i make a skill 20 and it slowly goes back down.
If you mean that you increase e.g. pace to 20 and after a while it starts dropping slowly, most likely you didn't increase his CA/PA as well. That would make sense because attributes will always try to balance out based on CA.
We don't have a "freeze attributes" feature implemented yet, so it's advised to also increase CA/PA when you want to increase attributes, to ensure they don't start dropping (as fast at least).
