Overwriting a Strife save game can cause invalid game state

Strife's save game system requires the engine to save the state of several levels of the game, so players can exit and return to levels, potentially through every level in the game.

If a player selects a save slot that already has another save game stored, and the save includes levels not yet visited in the current progression, files from the old save are not deleted during the overwrite, and it can severely hamper the playthrough, potentionally making the game unwinnable as a result. Workarounds include always saving to the same slot selected on a new game, saving to empty slots, or deleting directories containing unwanted saves first.

This is one of very few bugs intentionally not replicated in Chocolate Strife, and likewise Strife: Veteran Edition does not replicate it either.
