Weird unpack behaviour (2x, 1x, 0x)

[felipequintella]

Using it on Synology through docker.
Had Unpack ticked, for automatic unpacking the rar files downloaded.
I first noticed my files where getting weird permission settings. By digging out, I found that the downloaded files were being extracted twice. I think once by the "unpack" service from rutorrent, and another time I don't know how...
I decided not using unpack anymore, since there was something else extracting the files! It worked for awhile, the files still being extracted magically...
Now they are not being extracted anymore and I'm afraid to turn unpack on again and go all the way back to the weird permission problems...

Any ideas of what can be auto-extracting my files other than "unpack"?
