Some updates at the Sandwich farms!
First off, we've managed to get a farmer villager into the breeding chamber. This means the villager breeder and market is back up and running! Some things left to do:
- The farmer (apronless brown robe) needs to be name tagged to make sure he doesn't de-spawn by accident. This requires two players to accomplish, one to distract the villager (right click on them) and the other to tag them (right click with nametag in hand). I've been going the Three Stooges naming scheme, so this last one would be "Fake Shemp"

- The child villagers don't always go down the drain, maybe look into using fences to push the adult villagers closer together while still able to access the outer farm blocks.
While over there, I also noticed how crappy the minecart switchyard on top of the market was. One side has a tendency for laden minecarts to bounce between the switch track and stall mouth at least once before continuing down the line to an open stall.
So, I experimented, and found what I find to be a really really neat use of tripwire hooks:

z64's wonderful usage of tripwires
What's so great about this set up is that empty carts pass through the switch-yard effortlessly, there's no bounce back, and its
fast acting. Additionally, it's cheaper resource wise since each tripwire arrangement uses 2 iron vs. the 2.25 iron from using plain tracks, with a higher wood consumption.
I can definitely see this design being used in major metro rail station for disembarking players.
If there are no objections (and if I get around to it later this month) I'll try updating the switch-yard on the villager market with this design.
