    Description

      I haven't dug into this too much, but one example that causes it is:

      /effect give @e[type=sheep] glowing

      If there are sheep around, it gives out:

      An unexpected error occured trying to execute that command

      But the sheep do indeed glow.

      It also happened with a few other commands, but I wasn't able to see a pattern yet.

      The log contains this:
