Recently, I have attempted to update to a 1.7.10 workspace. I have gotten many errors while installing, and fixing them as I go along. I have been getting the same error even after I fix them all. Some files are downloading/being copied without permission to my user. After I fix that (by adding my user to 'Full Control' Security) for all the files, it automatically deletes everything in my '<forge source folder>\build\tmp\recompSrc' folder. Then, once done coping/downloading, I get the same security errors I just fixed. I'm not sure why it does this, does anyone have any suggestions?
