Everything about Treben has disappeared from the article Why The information was sourced and vital since Arnswalde took over Treben s function as the central market for the region which was also sourced No what was is in the article is that the construction of this Treben was discontinued Hence it s actually a fairly minor part of the story basically a who cares Are you sure you re not confusing yourself with your Trebens and Sovins here If Treben was a significant part of the story then I m sorry that just does not appear to be clear from your text Rewrite it and propose it on talk in a way which clarifies the situation This one might be just a simple failure of communication
