Yes I've had the same problems, it seems the villagers just won't fish when not being watched. I left the game this morning and the villagers had loads of food but when I came back on tonight they had none and fishing is open so why don't they fish when no crops or coconuts. Ive also lost the occasional hard working villager before they could get the totem too - most frustrating! Let's hope the patch will solve these problems when we get it.
