Ran smooth for me with about two hours of gameplay. The only bug I encountered was when I de-constructed an improvised backpack. It only dropped sticks. No rope or sack. Oh and the small hammer still won't mine stones.

I've noticed two issues with the current experimental: Small Hammer makes wood chopping noise when mining stone and more importantly it does not drop stones. Occasional barrel lid opening noise plays when near a barrel. This is very similar to the car pop bug except it seems to be a closer proximity.
