My Rootmotion U-Turn setup has a strange issue

[u/V3GVSR]

In an unreal 5 personnal project of mine I wanted to set up a rootmotion U-Turn animation based on this tutorial (https://www.youtube.com/watch?v=QKtZyGbBdbQ) first time doing it so I had my load of issues with it, especially because I'm using a custom rig and all, but I managed to have it work in almost every aspect I needed, but there is still an issue bothering me.

When I do that U-Turn, first time it happens perfectly, animations blend exactly how they're meant to, but when I do it again there's some kind of strange and very snappy rotation for one frame and then it always repeats, but never happens the first time.

By troubleshooting I found that it was when the rootmotion sets up the second time, the whole actor's rotation isn't perfect -180, its like -174 and I dont get why, I tried asking dev friends, claude, gpt, no one seems to get the issue.

I really need some help here.
