Repro Steps:
  • start Dota 2 workshop tools
  • enter a new game
  • delete all children entities of a hero
  • die and respawn
  • delete children of hero again

Expected Result:
Child entities would not be visible in game

Actual Result:
Child entities are visible in game

This seems to happen only on the fist game played after starting the tools. If I quit the game and then start another, this does not repro.
