I have noticed an item is highlighted light green as part of a timed order that was filled, and every time I merge and get that item it sits there as light green and has tied up the npc as well. I actually completed that order. I’ve noticed I tend to get a lot of sand castles and no orders pop up for them (when before anytime I had more than 3 of them sitting random orders for 2 or 3 would pop up and they don’t anymore). I love this game, but seems as tho there’s a few bugs that need fixing. They don’t really bother me that much and I continue to play anyway.
