[Error] NoMethodError

[DarkNova21]

Greetings! 😃

I'm new at the pokemon fan-game developing, and I started to use Essentials a few weeks ago.
I replaced default outdoor tileset with my own tileset and everything was ok, then I edited default map with my very own layout, etcetera. That was two weeks ago. But today, I maked a indoor tileset by my own, based on GSC's indoor tileset ('cause a tileset like that doesn't exists on the web) and I replace Player's House's indoor tileset with the tileset I mentioned before. Then I created two maps on a route. Why I mention this? 'Cause when I test the game, crash. This message appears:

I didn't messed up with scripts 'cause actually I'm learning scripting and I don't wanna touch anything related of, so I don't know why this message appears. On a forum I read that maybe it's because the size of the tileset it's to big, but I don't think that's the reason, 'cause this problem was mentioned by a guy with a 256×4800 tileset, when the default outdoor tileset's size is above 256×4800 and everything is ok. Any idea?:(
