Whilst on my server today, I noticed a new bug with command blocks.

When I run this command in a command block:
/scoreboard players remove @a7,~2,~21,10,score_points_min=25000 points 25000
And click a button to run it, my game will crash, with the error message in the included picture.

Each time I tried to reconnect to my server, the error message would appear, and I would be disconnected. I decided to delete my scoreboard.dat in my world folder, and it fixed the problem, however, when attempting to do it again, my game will crash again.

Steps to Reproduce:

• Create a new multiplayer server running either 14w03b or 14w04b.

• Create a new scoreboard objective named "points".
  • "/scoreboard objectives add points dummy Points"

• Add yourself to objective points.
  • "/scoreboard players add <username> points 25000"

• Give yourself a command block.
  • "/give <username> minecraft:command_block 1"

• Enter this command into the command block:
  • "/scoreboard players remove @a7,~2,~21,10,score_points_min=25000 points 25000"

• Power the command block.
