ladder bug (The Witcher 3: Wild Hunt)

How is "unable" expressed?
Doesn't the prompt ("E") appear?
It was so. Come close to the stairs and press "E" without prompting

He climbs the stairs, but cannot climb.

Alexey Melekhin
It is necessary without letting go of E, keep also W

no use, he doesn't climb the stairs.

Any staircase, or somewhere in particular? Is there a way up there?
In the Novigrad canals there are a pair of stairs where the hatch opens only from above, respectively - Geralt cannot climb from below.
Look for other ways;)

In in, the same thing. Suddenly he stopped climbing any stairs. So what's now

the task is the chosen one of the gods, there is a basement where the sword lies, I can not get out about there.

What to do? now on the island of fogs and the stairs in the lighthouse do not work, there is a hint but when you press "E" nothing happens.
