Access signs are very handy if placed on top of a chest to give another player access.However, if placed on the side of a chest, they do nothing. Well, except look like they give access to the same chest.For a new player, this behaviour is confusing. It results in frustration for buyers when chests can't be opened and the other player is not online, and for sellers when they realize this and need to reorganize their storage area and allocate more space to accommodate the signs. Access signs placed on the side of chests look much neater in a storage room, for example, and allow chests to be stacked on top of each other.It's become such a common occurrence for me to see access signs placed on the side of chests that I've taken a habit of expressly telling sellers to make sure the access sign is on top of the chest. And even despite that, I still get sellers putting it on the side of chests.I understand that there may be cases where an access sign is ambiguous about what chest it refers to. ie it's above a chest and on the side of another chest. In that case, we can allow access to all chests, or give preference to one of the chests, though I have never once seen an access sign placed in an ambiguous position.If the rule is left as is, I feel there should at least be a warning when an access sign is placed and no chest is present. This way the player can at least correct the placement right away.I have abstained from voting and want to see what the community thinks on this issue.
