Q. How do i update? Do i need to download both common and body files in case of an update?
No, only download the file having their version changed, that's why i have kept them separate for easy updating. If "Common Files" version changed then download that only. If body files version changed then download that only. Read the description on new file. If it says "Overwrite" then you just need to overwrite without doing anything else. If it says "Update" or "Uninstall" then read the description on mod page for update / uninstall instructions.

Q. Where is she? i cant find her in the given location.
Make sure you have latest version of skyrim OR wait for few hours by pressing T inside her location OR reload your save OR restart the game.

Q. Why is she having dis-colored face / body / hands?
Make sure you have installed both "Common Files" and "Body Files" properly. Make sure you have enough VRAM available to load the textures.

Q. Why is she replying that i already have someone when asked to follow?
This happens when your previous follower fails to dismiss properly. Type "set playerfollowercount to 0" in console and ask her again.

Q. Why my game is crashing as soon as i give her some armor?
You are using BBP/TBBP armor without a skeleton to support it. Download and install a skeleton like XPMS.

Q. Why is she not casting certain spells?
Either she is out of mana or she doesnt have enough skills to cast those spells yet. If this problem is coming after an update then simply restore default values of corresponding option via MCM. Also make sure you have SKSE version 1.7.2+

Q. Why Mod Configuration Menu is not appearing?
This is a common problem with MCM itself. Simply type "setstage ski_configmanagerinstance 1" in console.
