Undefined method length error?

[Kiedisticelixer]

This happens when a field encounter is generated:

Exception: NoMethodError

Message: undefined method `length' for nil:NilClass

PokemonBag:421:in `pbQuantity'

PokemonField:977:in `pbGenerateWildPokemon'

PokemonField:1009:in `pbWildBattle'

PokemonField:1473:in `pbBattleOnStepTaken'

PokemonField:1497:in `pbOnStepTaken'

Game_Player_:449:in `update_old'

Walk_Run:75:in `update'

Scene_Map:104:in `update'

Scene_Map:101:in `loop'

Scene_Map:114:in `update'

And this happens when the encounter is generated through Debug mode:

Exception: NoMethodError

Message: undefined method `length' for nil:NilClass

PokemonBag:421:in `pbQuantity'

PokemonField:977:in `pbGenerateWildPokemon'

PokemonField:1009:in `pbWildBattle'

PokemonDebug:753:in `pbDebugMenu'

PokemonDebug:297:in `loop'

PokemonDebug:823:in `pbDebugMenu'

PokemonPauseMenu:242:in `pbStartPokemonMenu'

PokemonPauseMenu:241:in `pbFadeOutIn'

PokemonPauseMenu:241:in `pbStartPokemonMenu'

PokemonPauseMenu:142:in `loop'

I haven't modified any of the scripts the error log lists. It started happening simply when I deleted some maps and started a new game. Trainer battles function perfectly. I started using a text comparer with my -small- edits and the stock Essentials and there is no difference in those scripts. Where should I keep looking?

Did you change how many Bag pockets you have? And did you start a new game after doing so, or did you assume that using an old save was okay?

hey maruno
im not the op but as this is such a recent topic ill quickly ask my own similar problem here

i edited the amount of bag slots and then (obviously) got the same error.
i immediatly knew that it had something to do with it because that was the only thing i changed.
i started a new game (i have never saved while debugging to begin with) and still got the error.

i have changed the bag slot for potential items so they dont appear in bag slots that dont exist at the start.
then i then wanted to test something else and then got the error from an encounter.

so as u already had a suspicion:
what more do i have to change to make a changed number of bag slots work?

if i should make a new post or post my modifications let me know.

thx for your time in advance :)

EDIT: ok got it working. i had a single **** typo in the reworked items file that assigned an item to a pocket that didnt exist.
