Apparently there's a cap to how many items you can place on your fields in general. I've expanded my fields to the final mine in my first year of summer.
Is there a way to expand how many items you can place on the fields? I have so much space on the second expansion and I barely had the chance to do anything with the 3rd expansion and already got this message, "No more items can be placed".
[edit] Never mind. Found out why. Didn't occur to me to certain items had limited amounts of set placement. Was trying to place a stone chest down and I guess I maxed out on the amount of stone chests that can be placed. It was the easiest chest to make so I didn't care to make the other chests.
