Android I keep losing my fish smokers.

Hello I'm pretty new to the game but I'm on year 3 and I've been encountering a problem on the Mobile version. My fish smokers keeps DISSAPEARING everytime I sleep. Is there anyway to fix this? I don't have SS because I thought I misplaced it the first time but on the second time this happend to me I knew this was a bug and not a mistake I did anymore.

I did some experiments with preserves jars and didn't get the same result. Here are the pics I will try again tomorrow and see if my preserve jars would disappear after I sleep or I genuinely misplaced it.
