Plants are no longer producing harvestables

Same issue here! was working fine, until i created this new household, a sim for my sim to marry. When i merged the household, my "Perfect" plants returned to "normal" and stopped producing harvestables. 

I do want to note that i didn't move the plants into the inventory prior to merging the households. I used the new household as the active household when merging the two. I think that is why i lost the "Perfect" plants.
