I caught a level 3 Dunsparce in the Dark Cave area in Soul Silver. The method of acquisition was a swarm. PKHeX (version 20210521) flags the Pokemon as illegal because it can't match an encounter from the specified origin game. Unless I'm missing something, this is simply because the encounter database states that the minimum level Dunsparce can be found here is level 4. My Dunsparce is level 3 but resources such as Bulbapedia and Serebii suggest that it can be found as low as level 2 during a swarm. Changing the met level to 4 results in the Pokemon being considered legal. Attached is a copy of the Pokemon data taken from Moon but it would appear the issue is reproducible in any generation. I checked some other Pokemon with lower levels during a swarm, such as Chansey, but found no issues so it's probably isolated to just Dunsparce (both Heart Gold and Soul Silver versions) in this case. I hope that's enough information to go off of. Thank you in advance. 206 - Dunsparce - EA098CD63562.pk7
