Dead and buried. It’s considered to be working as intended, because the endless corridor doesn’t exceed the guaranteed limit of 6 rooms. In case you are questioning your counting skills, the magic trick was to claim that repeatedly extending the path by another up to 6 rooms actually makes that several individual paths, so everything is just fine.
As much as the community was able to figure out, the bug only happens when a path hugs the border of the map, and it only rarely happens in such a situation. Incidents like these also convinced the community that reporting bugs that harm players is a lost cause, the best you can hope for is not getting ridiculed.
