Question about a warning from FNIS

[Echobaby]

After installing XP32 Maximum Skeleton Special Extended, I ran FNIS and got a warning that I don't understand completely, Here's the FNIS result:

FNIS Behavior V7.0 1/31/2018 9:15:04 PM
Skyrim SE 64bit: 1.5.23.0 - D:\SteamLibrary\steamapps\common\Skyrim Special Edition\ (Steam)

Skeleton(hkx) female: XPMS2HDT (115 bones) male: XPMS2HDT (115 bones)
>>Warning: Custom skeleton found. Select SKELETON patch.<<

Reading FlowerGirls SE V1.8.3 ...
Reading FNISBase V7.0 ...

All Anim Lists scanned. Generating Behavior Files...
Alternate Animation mods: 0 sets: 0 total groups: 0 added file slots: 0 alternate files: 0

Creature Pack not installed

1037 animations for 2 mods successfully included (character).
1 Warning(s).

It looks like FNIS is recommending that I select SKELETON patch. In the list of available patches, there is a SKELETON Arm Fix item with a check box next to it. Should I select it and then click on Consistence Check?

It means the arm fix. It will not throw this error if you select it.

Great! Thanks!

[DJLegends]

thank you it fixed it on original Skyrim.

Thanks. I had the FNIS notice:

Skeleton(hkx) female: Unknown (126 bones) male: Unknown (126 bones)
>>Warning: Custom skeleton found. Select SKELETON patch.<<

and the "SKELETON Arm Fix" did the magic!

126 bones? should be 115.

UPDATE: nm, I didn't see the update regarding this

Yeah they added more bones for smoother transitions or something.

When running FNIS it's just good practice to have the skeleton arm fix and HCK conversion boxes checked. Found in experience a lot of anim packs contain those older HCK files so even if it's not needed the conversion helps. The female/male folder box too.

I've been using FNIS for over a year, recently got this error for the first time, I used the arm fix option and that fixed the error/warning the first time. Now the error is back and checking the arm fix doesn't help. HALP HALP please. Could I have installed a file that overwrote something, that I then deleted left a gap?
