I was referring more to bug fixes that have been made in 1.9
The random water source issue is on our end and proving a nuisance to fix as the Fix itself causes a large number of issues.
The frame rate drop I'd need to see what you're building as I have no issues unless it's a ridiculous sized device.
I have experienced the FR drop as well with redstone primarily on large maps. Is this due to the limited memory on the consoles?
