Can't properly merge .oga with flac audio after foobar2000's converter

As you know .ogg and .oga files can be merged using standard windows command copy /b. And foobar200 can properly play such merged files and show individual tags.
But it seems when converting standard flac to flac in oga container resulted files lack some essential info in them and cannot be properly merged using copy /b command. When files are merged, resulted file added in foobar2000's playlist only shows few tracks tags, not all tracks.
When converting files to oga directly using flac.exe from command line, files can be merged as expected and resulted file shows all tracks tags when added to playlist.
I tested ith with few albums.
foobar2000 1.3.13 beta 2 (although i also tested 1.3.10 and 1.1.18 and problem is presented too), flac 1.3.1 binary from xiph.org, Windows 7 Ultimate.

The problem is related to Ogg serial numbers. There is a related recent thread here on the forums: https://hydrogenaud.io/index.php/topic,112560.msg927832.html#msg927832

When you encode one file at a time slowly on command prompt your individual .oga files get different serial numbers from the simple time based serial number generator. But foobar's encoder handles several files simultaneously so each instance starting at the same second gets the same serial number. You can add "--serial-number %r" parameters to get different random serials for each file and that will fix the issue.

PS: you can use copy/b *.oga "new combined file name.oga" to make the chained file.
