Can't get on steps

You can see steps made of refined gleam here - I simply get stuck on the first step. As soon as I jump on it I can fly up no problem. I have the same steps below the bridge causing no such problem, but I get on them from gravel-made ground. Here it’s ice I’m trying to get off - so maybe that’s the problem?

It actually works every now and again - but I get stopped on the initial step most of the time.

Can you give us the world name and coordinates? Thanks
