Rorgsachwaige
Rorgsachwaige is mentioned on the Wikipedia list but is coloured in red - which basically means that whoever entered this information on to Wikipedia couldn't find any information about Rorgsachwaige, whatever it was. Looking around on the internet, I also found very little, apart, that is, from a particular website on which there is a document entitled "2,500 Companies - Slave labour in the Nazi Camp System". Scrolling down through the document, I still, at first, couldn't find any mention of 'Rorgsachwaige'. However, I then did a 'Find on page' search from my Google Chrome browser and found this entry in a section labelled 'Transcript' (see screenshot above), which as it happens is right at the very bottom of the document.
As you can see, the entry says 'Rorgsachwaige Kdo' - 'Kommando' being a general term for a group of slave labourers. Scrolling up in this transcript, it repeats the general content of the document, which discusses the huge number of companies during the war that were assigned, and benefited from, groups of slave labourers working on their premises. It also says that the ITS information relied upon, to a large extent, questionnaires that were carried out, with varying effectiveness from region to region, and also that crucial documents are still locked away in some company safes. What complicates this even further is that many names of camps and locations came from oral sources.
I suspct therefore that 'Rorgsachwaige', referring to a Kommando, or group of slave labourers, rather than a specific location or camp, was moved around locations frequently or may have been deployed at one particular location, the details of which have been lost or are being hidden by someone or somewhere, or maybe even just put somewhere and forgotten about. This is assuming that there were any recorded details in the first place. It may be that the reference to the Kommando was all that ever survived the war. If 'Rorgsachwaige' was attached to a facility set up and operated by the SS directly, this facility would have been closed down by the allies at the end of the war. Thus it seems likely that no information at all will ever be found about Rorgsachwaige, and that only this reference to it survives.
