I've released a new version of my Minecraft Player/World Editor MCPlayerEdit v0.19. This release features the following modifications and additions:
- Added a `health` command which lets you set the player health (also a god-mode)
- Fixed a bug where only supplying an item ID to give/remove would not give the maximum stack size but would give a stack equal in size to the item ID specified.
- Fixed a bug where adding non-safe items to the inventory would give a stack size of 0.
You can get the new version Here.
