[Error] scripting error I don't understand

[SumiInk]

So I playtest the game and I'm trying to test out Aegislash's ability by entering a battle. But when I try to encounter a wild pokemon, I get this error message:

---------------------------

The pokemon essentials wiki describes a similar error message, but it happens when there's an outdated essentials or Windows, which I don't have. And it can be fixed by disabling the time function in the old versions of essentials, but the script is different in 17.2. So.... idk what to do. When I tried to enter a trainer battle, it worked at first but then the game crashed and showed no error message when the other trainer tried to send out their pokemon.

For reference, the script that I've changed recently is adding Zygarde cubes using the method in this thread: https://www.pokecommunity.com/showthread.php?t=398562


The thing is, though, the last few time's I've tested things it didn't involve battles so idk how long this problem has actually been there. It could have been caused by different scripts. If someone can at least explain the error message to me and what the issue might be that would help a lot.

Nevermind. I just found a backup and started over on some things. Seems to have worked though I'm still not sure what caused the error in the first place.
