I don't dare making any assumptions and I thought long and hard before putting down these lines.
The last time I had contact on Skype with him was September 11, 2019. From that day on the contact broke off completely, i.e. he did not appear on TLF, BLF or Skype ever since. Jacky Zhang (LuckySun/WildTrail) also lost contact with him. :-( Before he disappeared, the Docc told us here on the BLF D80 V2 thread that his mother was expecting a difficult medical operation. In that same time he informed me that he suffered from serious health issues that I don't want disclose in detail for the sake of his privacy. Whatever happened to him, let's put our best hopes in a speedy recovery for him and his mother and that eventually he will show up again on BLF someday.
