time for crazy hypotheses - the hero mod is broken, the paths to the hero's models in the character file are incorrectly written + there is a file "fixing" another hero's character (or fixing the hero's own MapObject), so when it's deleted, the other hero breaks, but that sounds totally unreal
I copied from another hero into the damn Korder file
<Model href="/Characters/Heroes/Dungeon/Kaldoin/Raelag_LOD.xdb#xpointer(/Model)"/>
<AnimSet href="/Characters/Heroes/Dungeon/Kaldoin/Raelag_LOD-adv.xdb#xpointer(/AnimSet)"/>
....

<HeroCharacterArena href="/Characters/Heroes/Dungeon/Kaldoin/Raelag.(Character).xdb#xpointer(/Character)"/>
<HeroCharacterArenaMelee/>
<HeroCharacterAdventure href="/Characters/Heroes/Dungeon/Kaldoin/Raelag_LOD.(Character).xdb#xpointer(/Character)"/>
<HeroIndividualCamera/>
<CombatVisual href="/GameMechanics/CreatureVisual/Heroes/Warlock.xdb#xpointer(/CreatureVisual)"/>
which means that Korder's Characters folder is no longer in use, and it can't have any effect. What's in use is Kaldoin's Characters
where Kaldoin works correctly, but this Telph is still invisible
