Whenever i play singleplayer,theres a chance that i got the bug,which makes my game slower,like the moving speed of everymob,the delay between each hits from me to the mobs,items and mobs falling slower.Also when this occurs i get really laggy,even though i install performance boost addons but it didnt really help.Idk if im the only one experiencing this but if anyone also happens to got eith this bug plz tell mojang to fix this on the next updates its really annoying!!(also this occurs on the mc emerald tycoon)
