From The Battle for Wesnoth Wiki
- The level 3 Sentinel stats in the Legionnaire line must be edited, currently there are a copy of the level 2 Keeper.
- The Great Wizard line is obviously the highest part of the Wizard tree. Wrong unit ID make it broken:
- In the Wizard advance_to is set to EOM_Great Mage while the next level's id is EOM_Great Wizard
- The Protector and Divine Knight lines does not have any level 1 unit to start from.
- Do these lines fork from the Legionnaire tree ?
