Villagers won't trade, villagers/wandering merchants fly away when touched, turtles won't breed, lag issues

Any time we have tried to trade with a villager, it will not trade. The trading menu will not populate. Wandering merchants also do not trade, as they both just fly straight up in the air and disappear. The turtles will not breed/drop their eggs since all of this started as well. Not too sure how to fix this as we haven't seen any mention of any similar situations. Some ideas/suggestions/thoughts would be greatly appreciated! TIA
