the top of a port crane is floating above the base of the crane (see provided pics). Affected is the crane in Berezino (131 052), maybe this is an issue with all of them; did not check others so far.

So basically this (http://img.dayzdb.com/img/buildings/land_a_crane_02b.jpg) is floatring on top of this (http://img.dayzdb.com/img/buildings/land_a_crane_02a.jpg).

here my pics for proof:
