The Beta 13 Part 2 is here, enjoy. (Link Removed. There's a newer version available in the main post.)
Aethestode suggests to start a new savefile. You can resume a Beta 13 Part 1 savefile, but bugs might happen.
By the way, my guide about Side Chapters Starting Points and the Youtube Playlist linked inside of it have been updated with the release of the Beta 13 Part 2.
I'm sure I didn't record all the new Side Chapters yet, but right now I can only think of 2 that I'm missing.
The pokémon location guide was also updated, so make sure to check it out.
Oh yeah, and I wrote a new guide too. It's the list with the locations of the TMs and HMs that are currently available in the Beta 13 Part 2.
The 3 guides are linked in the main post under the "Guides" section.
Savefiles from the previous patch are compatible, but please make sure to interact with the Glitch Cleaner in Red's Room.
This patch contains a new little event.
Note: Several glitches that you've already experienced (like getting a Nurse Chansey with no abilities, no attacks and low stats) won't be fixed.
The glitch cleaner cleans up the flags and fixes some several gamebreaking issues.
