Ok guys, a couple of things.
Firstly, Plotpoles.
Once you place a plotpole to build, you MUST add yourself to the pole and the pole is to stay where it is. If you remove it to place it somewhere else within your base you run the real risk of not being able to remove previously built items, not being able to build at all or even having you base decay around you as you will have lost the ability to maintain it. To that end, I am turning off base decay until a fix for this is found. Rest assured this bug is on the priority list!
Secondly, the new skin trader.
Our new skin trader is located on the map at Blasflue, west of Munchenstein. He sells most Overwatch and Arma military skins. This trader will ONLY accept 2 x 10oz gold bars for each skin. So, you will have to stop off at a building supplies trader first to BUY 2 x 10oz gold bars of you don't have them already.
Also, and this is important, you MUST REMOVE YOUR BACKPACK BEFORE BUYING A SKIN otherwise if you have a backpack on, he will take your money and give you nothing. When you buy a skin you must put it on BEFORE putting your backpack back on. Also, you will not be able to wear skins you find in barracks, etc UNLESS you go back to the skin trader and BUY the base skin at the top of the list and put it on first.
If this is not to your liking, don't buy a skin from the trader in the first place, just continue picking up and wearing the standard skins you find.
So, now that you have been told about plotpoles and the skin trader there is no excuse for not knowing :)
