I have read some of the posts from the Reddit link @Khaos77 has given and the actual poster himself admits that it is his fault and has some suggestions.
Basically it's caused by my own mistake, because of the server power fail... I though that with my file backups I'm really safe... already have some suggestions to improve the system:~snip
~I'm just a naive person to trust that technology so much, it's my own fault. Btw they are doing a great job, coding as much as they can.
At least he is still positive with regards to the technology, which is Bitcoin, and knowing that there are still bugs to fix in it.
The Bitcoin Expert - Luke Dashjr (based on the badge that he has) is actively replying to the post and he said that ZipoTim is trying to claim an old state on the network, making other coins to be his if I understood correctly, ended up the other way around losing all his coins with it.
In the end, at least that ZipoTim admitted his fault, probably has a lot of coins because of his calmness during that event. Still clinging into hope it seems.
