- Fixes a few bugs from the last commit, namely:
- The guy who gives you the Pocket Lapras having bugged text
- Being able to use it where you shouldn't (Cycling Road, Seafoam before the boulder puzzle)
- Pocket Lapras not having an item description
- As well as this, automatic item sorting has been added. Just press Start in the bag menu and all your items will get assorted into a convenient list.
- Changed a few item descriptions since some of them didn't terminate properly
- Freed up some space in the Home bank
