I'm reporting a very serious nasty bug that have cost me a huge in game lost ever since the new 1.18.0 update. Every mob and none wall attach entity like, boats, minecart, armor stand... have ended up vanishing after a save & quitting. I've lost many useful entity such as villagers, powerful spared armor and every pets because of it. I'm playing in a single player world, so it's not like if someone else would grifed me by removed my entities. It never did that before until the recent 1.18.0 update. So as much as it is a fantastic update, it also has brought in a really nasty world griefing bug which needs to be fixed ASAP.
