Hello to everyone here,
The "issue" of brackets for S57-73 being in other set of servers than the supposed 38-169, is, as I mentioned before, not a bug.
It is caused by the servers being held by different machines (servers, so to say, or computers, if you prefer to call it that)
The brackets are set in accordance to this factor.
Have a nice day everyone, hopefully this clarifies the reasoning behind brackets being the way they are :)
