Would be possible to add a button or option to revert to a "pre-patched" condition for when there are issues with new patches?

I think I have done it in the past by renaming the "Landfx.bak" file in the LandFX file folder to "Landfx.vlx" - is this correct and will it still work?

I think a "revert to previous condition" button would really be helpful for those times when a patch breaks something and issues are encountered in the off hours...

Thanks much!
