Float Variable with stuck value

Hey, In the few years ive spent in unreal Ive never seen this…

Its a pretty basic setup for testing. Ive dialed it right back

These 2 floats. Just absolutely refuse to play ball and I have no idea why

No matter what I do. If I connect a print up to this it always returns 155

If I remove the floats and hard code in the numbers its fine.

If I make a new variable it works fine.
If I directly print the variable it prints 155

What the heck

Ok…I renamed it thats it. and now its working…

Can anyone explain this madness? Ive searched for references etc and theres only one out there.

Edit:
Some bots and threads ive read are saying its basically a rename under heavy iteration can cause this.

Apprently quite rare. so I guess Ill feel lucky today…45 mins of luck xD.
