Hi. I can't stand no more this bug. I played on my Minecraft 1.14.4 world for few weeks and this bug still annoy me very much. In short, sometimes, a chunk becomes bugged, I don't know why, but the affected chunk won't update properly and it affects all entities. For example, I can't pick up blocks in bugged chunks, I can't kill / interact with mobs, entities like arrows, fire charges, wither heads. The only mod that I use is Optifine and when I enter in a bugged chunk I receive an error saying "Open GL Error: Entity 1281 (Invalid value)". I really hope that this bug will be fixed in the 1.15 version. See this video below for all details:
