Rain, night, villagers and farmers without access to bed, workstation or farm land causes lag

There has been a lag issue for some time when it rains and generally at night. A combination of both means it is unplayable. Again, an issue for some time but more severe now, if there is empty farmland and a farmer cannot get to it that also causes a severe lag. With the addition of beds and workstation the problem also occurs when a villager cannot get to its bed or workstation. The lag means that sound effects disappear or are lagged, broken or placed blocks do not render properly and everything slows down to a jittery pace. This will happen during daylight hours.
