Don't worry about the thread, since we are using github we can track the issue on it now. I think we shouldn't even open threads with bug lists anymore, anyway who doesn't have a github account can post in this section, opening a new thread for the bug or open a small list if encountered multiple defects.
The important is report the bugs, how/where its secondary
Regarding the bug that you reported, try to rehash the files and check if the "neosharing" turns on after hashing. There was a lot bug about hashes/hashing in the 0.49 iirc, maybe that's why "old" files aren't shared while "new" seems ok.
I am not sure, anyway tomorrow D.X. will surely take a look.
