I lost all my proficiencies

Hello,
I had a farmer character with stocks and Cultivars about 16000 and other proficiencies were from 5000 to 7000, I was KO with 10 criminals and wasn't able to get up because I was on the territory where I made the criminal, so I decided to log out and login later,another day. Today I logged in and found that all my proficiencies are 500 now, every proficiency and I still in KO.
I think I should describe what I did before KO - I decided to check if brazers attack the character who built it, because my friend told me that they don't. So I left my town, turned the criminal on and started to open my chests, when I got 10 criminals brazers started to attack me, so I know that they do now
. I invited my character back to town but brazers KO me anyway. So I was KO on town territory, on my own claim territory.
I understand now that all that time I was offline my character got up and KO again, and every time he lost 2 different proficiencies untill he lost all.
I'd like to ask is it a game mechanics or the bug?
Is it possible to get my proficiencies back if it is a bug? Could admins do that?
