Latest Patch 1.7_01 BETA - Link on front page on site
Should you be riding a minecart stopped on an unpowered Powered Rail, you will find yourself unable to get out and about. Placing Rails in North/South way, followed by placing some rails on the side (and for that reason making a curve) ends up in no curve. "Outside" water sound still plays when under a glass shelter. In addition, Wolves under a decanter or glass roof during rain will be perpetually stuck in the "shaking" animation (proven for multiplayer, unknown to get SP).
