Breaking Shut Trapdoors Generates Endless Entities

I was building my bee farm when suddenly i was hit with the worst lag i have ever seen, this was on a singleplayer world and i have 8 gigabytes of ram allocated to my game because i just like that sort of buffer to stop lag. when i checked the f3 menu i noted how the entity count was skyrocketing it went from 120 to 40,000+ [Edit: The real issue is this message from logs "Received passengers for unknown entity" occurs after breaking a shut trapdoor in survival]
