Unable to climb down the specific ladder on pier crane in Berezino. There are several ladders on a crane but only specific one is bugged.
I dont know if all specific ladder on the all pier cranes are affected or only this one.
(One workaround how to get down the crane is by jumping down on the roof of control room which is few meters below you.)
Check video and image for location.
