// A lot of replays have messed up class hierarchies, commonly giving
// both Engine.TeamInfo, TAGame.CarComponent_TA, and others the same id.
// Some ambiguities may have become more common since the 2016-06-20 patch,
// but there have always been issues.
//
// For example, from E8B66F8A4561A2DAACC61FA9FBB710CD:
// Index 26(TAGame.CarComponent_TA) ParentId 21 Id 24
// Index 28(TAGame.CarComponent_Dodge_TA) ParentId 24 Id 25
// Index 188(TAGame.CarComponent_Jump_TA) ParentId 24 Id 24
// Index 190(TAGame.CarComponent_DoubleJump_TA) ParentId 24 Id 24
// Index 30(Engine.Info) ParentId 21 Id 21
// Index 31(Engine.ReplicationInfo) ParentId 21 Id 21
// Index 195(Engine.TeamInfo) ParentId 21 Id 24
// Index 214(TAGame.CarComponent_Boost_TA) ParentId 24 Id 31
// Index 237(TAGame.CarComponent_FlipCar_TA) ParentId 24 Id 26
// Problems:
// TAGame.CarComponent_Jump_TA's parent id and id are both 24 (happens to work fine in this case)
// TAGame.CarComponent_DoubleJump_TA's parent id and id are both 24 (incorrectly picks CarComponent_Jump_TA as parent)
// Engine.TeamInfo's ID is 24, even though there are 3 other classes with that id
// TAGame.CarComponent_Boost_TA's parent is 24 (Incorrectly picks Engine.TeamInfo, since it's ambiguous)
// TAGame.CarComponent_FlipCar_TA's parent is 24 (Incorrectly picks Engine.TeamInfo, since it's ambiguous)
// Engine.ReplicationInfo and Engine.Info have the same parent id and id (no ill effects so far)
//
// Note: The heirarchy problems do not always cause parsing errors! But they can if you're unlucky.
