Help with a error in game

I’m currently playing a rpg maker Game names niramare quest, using joiplay i play in android, everytime i use a spell like gold rush, it shows me this error message, Could someone help me figure out how to fix this?

Could it be due to just one skill, “Gold Rush”?

What I can think of is that this game was developed for PC, not Android. Even if you use Joiplay to play it on Android, it’s not 100% guaranteed. The game might use plugins or scripts that only work on PC, causing malfunctions on the Android system.

If you want to continue playing, you should avoid using skills that would enable such plugins or scripts, or find the latest version of Joiplay.

If you download this game from an unreliable source, you should be wary of malware.

It’s not only that skill, Even when enemy use spells gives me the same message

The error means that the game is trying to read a list and find out how long the list is. The list does not exist. This is a very unspecific and uninformative error and only the developer can figure out anything more specific.

You have better chances shooting the dev a message that you’re getting an error from using Gold Rush while using an emulator. The emulator shouldn’t be a problem because the game can apparently create and read data from every other list properly.
