In 5E’s defense, I’ve been playing since AD&D, and I’ve never had as many sessions, with so many people, and had so much fun, since 5e. 5E made D&D accessible, and that’s a good enough reason for me to DM with it.
The worst bug I’ve found is where the UI will disappear for a single character in the middle of battle, and it seems to be triggered by leaving part of your party out of the battle and having them join during someone else’s turn? It happened to me twice, and saving+reloading fixed it every time.
Also, they’re killing some fun bugs, like the mundane chest making everything you put in it weight less.
