Chains of Conditional Command Blocks don't work properly

Repeating Conditional Command Blocks have very strange chaining properties.

Falling Sand with Time!=0 removes matching blocks on the client side.

The wildcard * fits into wrong commands without error.

Scoreboard players don't reset properly when objective gets removed.

Pickblock does not recognize NBT data of items in player's inventory

The new {selector:"@..."} tellraw feature fails on failing selectors!

The @e selector is buggy in "/scoreboard player" if you specify "type=" and "c=".

Minecarts riding other Minecarts stack downwards

"/fill ... replace ..." doesn't parse correctly for blocks that support data tags

Weird rendering glitch for falling sand containing stained glass
