A few users of my game reported this error message when sorting pokemon in the box. Here below is the error they get in the errorlog. It seems to only happen for a few starters from what they have told me. I havent been able to replicate this error myself however.
[[DBK] Animated Pokémon System] [006] Battler Sprites.rb:63:in `width'
Here are lines 62-66 from the battler sprites.rb. The bold line is 63 which is where the error lies I think?
else
newWidth = [(@oldbitmap.width / @mosaic), 1].max
newHeight = [(@oldbitmap.height / @mosaic), 1].max
@mosaicbitmap2&.dispose
@mosaicbitmap = pbDoEnsureBitmap(@mosaicbitmap, newWidth, newHeight)
