Edit: Found a game breaking glitch in Silph Co right after the Secretary battle. Trying to fix it now, right now it'll crash the game after the battle.
Progress: Alright, it looks like there are a few areas where people commonly have problems which are
1: Getting too many checkpoints and accidentally skipping the "Find Clues" quest which also gives you the Lockpick
2: Having too many checkpoints and having to give the pokemon back to Redra immediately after getting it (and sometimes crashing the game)
3: After the Redra Museum quest, returning to those areas can have music problems, crash your game, or show text it didn't (or wasn't supposed to) show before
I've been working on preventing the checkpoint issue by forcing your checkpoints to be a specific number as you progress, so if you had 14 somehow, but talked to Maxx outside the PokeCenter, they would be forced down to 12. And then you could progress as normal.
But for the people who already HAVE the checkpoint issue...
If you complete later quests, and then go back to earlier quests (like finishing the Maxx pokecenter quest and then you go invade and finish Silph co) then you might break your game because you won't be able to get those checkpoints back once they're forced down.
I don't know if this has happened yet, but it's a possibility. If it has happened to anyone let me know and I can figure out a way to fix it.
Also...!
I've been testing TM/HM stuff and so far it works. If it keeps working I can start including TM's on the 3rd floor of the Department Store and the Game Corner! So you can finally teach your Pokemon more moves than just the ones they've been getting by battling and leveling uo.
no i mean i never made it past the sixth floor and and i was able to leave, but now that i think about it i may have screwed up the game in the pokemon mansion. i used the cell phone and was getting dialog from later quests. after i got back to the hideout i was able to go right to the silph co. mission instead of going to find Redra. When i did exit silph co on accident i was unable to go back in and max was waiting at the pokemon center in saffron before i even triggered the actual quest. i was not able to go into the lower portions of the center i was just told to leave and then when i went back to celedon to try to teleport back into silph i triggered the phone call for the pokemon center mission. I'm sorry for not really explaining what i meant in my previous bug report.
luckily i had made a save from earlier in the game so i was able to get back to silph without much issue. this time i didnt make the same mistake in the mansion and the game ran fine
I'm glad you had an earlier save file!
I've now also fixed Maxx so that just talking to him will correct your checkpoints to 12, since you're only supposed to see him at 12, and if you see him and have more than 12 then something's gone wrong.
And the Pokecenter mission only works at 12.
