I'm pretty sure we only get questions along these lines because people watch others play the game and see Spectre. In which case, I'll clarify this once more:
The Spectre mystery gift ended last year and will not be returning. Altaran Charmander in general will be obtainable in normal gameplay in future versions. This means that missing out on Spectre does not mean you won't ever get Altaran Charmander.
Based on that error, that is an issue with Altaran Sigilyph having been implemented, but its moveset not set correctly.
That being said, that was an issue we were well aware of and it has been fixed since we released the 2.2 core. The fact that you've encountered this issue suggests that you only downloaded the core version and did not patch as instructed as on the download page (and unfortunately, multiple times in this thread... and Discord server.... Thanks guys....). Use the launcher to download and apply the patch to your game. If that does not work, you can download the patch from the download page itself and attempt to manually apply the patch by unzipping the archive's files directly into your game folder, replacing the files as prompted.
