Whenever I kill a player and his body falls through a table or wall, I am unable to access his inventory. This issue happened both in vanilla and modded servers. I was able to see the players chest and head, as well as feet on the other side of the wall. I could also see the "[+] Survivor" icon, and no matter how much I tried to constantly hug the wall, his inventory would not show. I attempted to go in different positions and try different angles and it wouldn't work. Only fix to this issue would be to cut up the player with a knife and then get his loot from the ground. This is heavily influenced on the position the player falls in. If he has his belt area inside of the wall/table, then I am unable to access his inventory.
