W3C log gets overwritten on restart

[aejirs]

Hello.

I am using Shoutcast DNAS/win64 v2.0.0.29 (Jul 31 2011) and it appears that everytime the server gets restarted the current w3clog file gets overwritten without a rollover.
The normal sc_serv.log is rolling over correctly at each start.

Is there a way I can prevent this from happening without manually triggering a roll over each time?
I have read the documentation but have not found anything w3c related besides enabling/disabling it.

The w3clogfile itself is a bit weird aswell, it is missing a header and has an empty line every other line, a client of mine gave me an example of his w3c log file (using version 1.9.8) and it appeared to have a correct header.

I am writing a parser for said client and need complete log files to do this.
