Plex cant find my series, because it contains a dot as the starting character

[OttoKerner]

Files not scanning when . at the beginning of the file

Under Unixoid OS’s/MacOS/Linux (that includes FreeBSD), it is defined that a folder or file name starting with a dot is ‘hidden’. Since Plex is written to run on many OS platforms, it does obey this convention and ignores file names starting with a dot.

I guess in this particular case, when there is another show of the same title, released in the same year, that you have a justified reason to use ‘Fix Match’.
