When I add an nzb to SabNZBD and let it process, it replaces the spaces for an dot, have a look:
By the way, I do not have the option enabled (either in Mylar or in SABNzbd) to replace spaces for dots.
The dots being replaced is internal use for Mylar only - it has no bearing on what the nzb name is or the filename itself (it's used by Mylar to locate the proper issueid, which was stored with the nzbname that Mylar generates as the parameter after a sucessful search result). The fact that it can't locate the nzb within its own db. Usually because of one of two reasons:
1 - You are downloading the file outside of Mylar, but then are attempting to post-process it with the ComicRN.py script. Mylar doesn't support this functionality. Either download it using Mylar or if you need to do it manually, use the manual post-processing option located within the Manage tab. Enter in the folder to where the file(s) are that you want to be post-process ed and let it go. It will only do post-processing for series in your watchlist.
2 - Blank out your Sabnzbd Download directory option within the Mylar configuration, save it and then restart Mylar. You only need to specify a download location if Mylar and Sabnzbd are running on separate machines)
I'm going to just guess it's because of option 1, but again just a guess at this point without knowing how you have things setup.
Thank you for your response, I'll have a look at it.
I've created an extra category in SB to move the files to a single dir, and let Mylar scan this folder.
