Immediately after logging in to official and private DayZ servers, there is a bug where player-built environmental objects like fences, doors, walls, and Improvised shelters, are physically loaded into the game before the actual environment which allows me to see all nearby player bases before any of the actual environmental objects (grass, trees, houses, etc.) have loaded. Unfortunately, this is detrimental because any player who is oblivious to the location of your supposed "hidden" base would be able to clearly see where you have set any base building objects through all of the built-in objects on the map. I feel as though this bug defeats the purpose of building a hidden base to protect my stash in the first place because as soon as you set a base building object on the map any player who logs in near you will be able to see it through all the preset objects on the map.
I think what should be done to fix this bug is have these player base building objects initially be loaded invisibly or make the standard environment which includes trees, houses, etc. visually load before player's bases load. This would make bases not be able to be seen through walls and also prevent players from glitching through a players base before their walls have been loaded in.
I hope this information is helpful and if you have any questions or comments I would be happy to help!
