The new changes are epic but there's some notable problems.
- The front door Auto-Locks after the first use, and can't be opened unless a "Special key is had", even gems won't open them like they used to. First try had to have a DM open it for me to enter after a PC did it prior, and on my second reset attempt after getting trapped was auto-locked inside the room not letting me out.
- The crate autospawn creates some interesting use of pathways but at the same time has the problem that so many of the rubble mounds did: Namely they spawn and can block all possible paths. Maybe destroyable with area of effect like the mounds were (Couldn't try) but otherwise no option to destroy the blocking crates.
This just happened to me, too.
