I’ve noticed a problem that sometimes happens when trying to plant a proximity mine and it would simply not place and the mine stays unused. This becomes an issue where I sometimes would plant it down with enough time for it to catch someone who may be coming down a certain corridor while I run down it, preventing my quick trap, or more importantly when I throw it down at the feet of my enemies where I then would shoot detonate it but if it does not plant then I am pretty much done for. It does sometimes happen when planting a mine too close to a wall but most of the time it would fall to the floor of the wall normally and at least it is still there to do its job rather than not appearing at all which can occur in other places where no major wall is present.
