a lil heads up as per last update from Juji our next update will include Prelude of War but he didn't specify upto which cut off point that would be, DIL said this about that: "overseas versions (PtW) should be up to 2019/01/02, at least, we'll have this version for Live + Classic updates January 2"
this means we will not get the ISS changes etc. included or any of the other ones posted in this topic since then as those happened on 23rd January and onwards..
I do recommend rereading the Korean patch note details as there are quite a few changes coming that will affect the game greatly
