I've been in the house overnight a couple nights before the changes, and there were no monster spawn issues at all. If it was zombies the usual mistake is to build the roof out of full blocks and then forget to light it. Simple enough to fix. Personally I prefer the open look like it had before but not a huge deal. Alternatively use glass instead of cobble -- I carried a couple stacks of sand back from the desert last night and would be happy to go get more. In fact I might have left some glass cooking...
We need more chest space if anyone feels like expanding one of the floors a bit.
I'm thinking about doing an AFK autofisher. We were using those on the ms vanilla and getting tons of enchanted books, bows, and fishing poles.
Also I'm finding mining pretty inconvenient in the immediate area, chock full of caves down there. Ultimately we'll probably want several stacks of diamonds to gear up everyone for the dragon.
For enchanting, use books and then anvil them onto your gear, that lets you pick and choose. Which also means steak is on the menu though we'll obviously be flush with food and never have an issue getting more. Especially after I start getting stacks of fish as a side effect of getting all those superpowered bows.
This vanilla has arrows with effects, right? Do feathers drop or do you still need to kill chickens? Or if someone finds a skellie dungeon we can farm arrows that way.
