So far, bonemeal makes grass grow (like brush) and can be chopped for seeds (only way to get seeds now).
Reeds don't block arrows (apparently this was a GLITCH...)
And non-shit old school awesome-sauce booster carts are fucked.
The trick now is to place one powered rail every 32 or so blocks. So, one powered rail section + 1 RST, or you could do plates if you want to be fancy.
Unpowered rail sections stop carts.
If you fucking take carts from Alpha, replace them when/if you can.
Much grassy ass. Bitches.
OH... going to be a booster rail party at some point. Bring gold, redstone. Thanks.
