For the past few weeks, I've been cooking food on the stoves, including ones for goals. I've even put out stoves to build, but whenever I come back a few hours later to check if ready... the food is half prepared and the stove disappears. It's like I'm wasting coins by thinking the food is cooked, when it's not.

Is this a syncing issue? My WiFi connection is strong! Does anyone know how to solve this?
