Same as v4b, but deleted navmeshes cleaned and lighting improved by Ablaze666 - thank you! Changelog and all files included. Unpack to your Data folder and overwrite.

An update to v2 (only main library and The Rift) by AaronOfMpls to remove the WIP cells that (in newer versions) later became the Whiterun and Reach libraries, and some standard cleaning with TES5Edit. Thank you <3
