A situation arises when a save editor, specifically PKHeX, cannot validate a Pokmon encounter as legitimate based on the data present in the game it originates from. This commonly manifests as an error message indicating that the encounter’s characteristicssuch as its location, level, ability, or held itemdo not align with the parameters established by the original game’s code. For example, a Pokmon caught in a specific area using a particular method (e.g., fishing) may be flagged as invalid if its characteristics deviate from what is coded as possible in that scenario.
The significance of this discrepancy stems from the potential for save files containing illegitimate data to cause issues within the game itself, or when interacting with other players online. Generated or modified Pokmon that do not adhere to the game’s rules can introduce instability, potentially corrupting save data or being flagged as illegal in online battles and trades. Understanding the root causes of these validation failures is crucial for maintaining the integrity of the gaming experience and adhering to the terms of service set by the game’s developers.
