After a couple of lengthily tests...
I found some inconsistency in dupe checking, which was probably caused by links created/collected with different versions of VK.com plugin over the past weeks.
Also a mix of below formats had impact on the dupe check results:
1. **External links are only visible to Support Staff****External links are only visible to Support Staff**
instead of
2. **External links are only visible to Support Staff****External links are only visible to Support Staff**
Links were collected based on different LinkGrabber inputs:
1. as result from crawling a playlist
2. as result from grabbing links with Firefox LinkGopher
Anyway, when using the current JD version, after cleaning all old test 'link collections' from the past weeks there is no such problem anymore, as reported.
So, just disregard my report.
