[Scripting Question] Lots of Error Messages when i using the Online System

[LightRO]

Hello everybody,

I have a problem with the MRMXOS and the new version of Essentials.
I use the package of Legends of Kanto with the online system. But now thought that I can also put it on Essentials 17.2.
Unfortunately that was a mistake. I can start and run the game, fight, talk, catch etc .. only when selecting the Pokemon, whether under Pokemon, Pokedex or PC) the game crashes again and again with the error message stored in the spoiler.

Error Code:

Spoiler:

PScreen_Party:664:in `loop'
PScreen_Party:696:in `pbChoosePokemon'

And when i delete all new extra script files than its working.
I think it's up to the DB, right? Maybe you could help me here.

Best regards,
