Player shoots off into the sky..........Why?

So I have set up mostly everything I want in a single level, Everything is awesome…Then 4.10 updates to 4.10.01 and now when I jump on my character I shoot off into the sky.

I was using the basic fps character BP. I went into it and tried to set the jump z velocity to 0, It didn’t do anything, character still shoots off into space.

I set jump and stop jumping to the press and release of space bar (hoping just redoing the nodes for jumping) would help…it doesn’t…

What could be wrong?

And how can I fix?

give me pics of the character movement details in your blueprint please, i can help you better then
