Freeport 5 in Omega 41 system is not at the location detailed in the Discovery Wiki. It's still in Omega 41 though. This location refers to Freelancer 1.0 possibly. I think maybe Discovery creators move places around on purpose.
The wiki is always sketchy at best on whether it is fully updated to the most current mod version. Because there is no one who full time maintains it, which would be a rather boring and unfulfilling job, it is mostly just haphazardly updated as people feel like it.
Your best bet would be to download Freelancer Companion to get more accurate info.
The Wiki is waaaaaaaay outdated. It is not being updated because the mod version is not finalized yet, and people don't want to update it over and over again when a new update comes out. The Wiki will be fixed after the final mod release of the current mod version.
