I'm new to tera-finder,and I generated a shiny Gimminghoul by what some tutorials told to do. But now a problem happend that its seed is invalid when I checked it in Seed Checker. Here's my procedure showing how i generate it:
1. Opened tera-finder by Standalone not from pkhex, and only imported portal event but no game sav file
2. Let Raid Calculator generate shiny gimminghoul seeds and I randomly chose one to export as a PK9 file
3. Opened pkhex and imported this PK9, recording the pkm's information
4. Back to tera-finder, typed pkm's information into Seed Checker and check it. The output showed the seed was correctly calculated, but "INVALID" followed it
I'm confused with this phenomena
