4.85 wtf?

Fellow Hoodlum, I know many people who have encountered issues with the common.dll file. It simply refuses to copy over for some people with FLMM.
All that FLMM does is well, copy and paste. It renames the original files by putting an flmmbak or something similar on the end of their names. When you de-activate a mod, the original files are renamed again back to their original state.

In the end up, it is the exact same as copying and pasting, except some files may be left over etc.
I use FLMM but have had issues like this before and I've found that copying and pasting is no different than letting FLMM do it. The only issue would be the various 'options' that you can choose when you activate the mod, you can't do it that way.

Don't mean to be rude or anything, just trying to help:)
