I've added more splits to the auto splitter: Bishop, Living Rune Block, Bossling, Shruboss, Remedi, Furious Giga Slime, and Elder Boars. If no further changes occur, you need to beat these bosses in addition to main story ones for All Bosses category. You need to manually enable these splits from the Settings menu in the Splits Editor.

Except for Bishop and Rune Block, the added splits use a new detection method involving quest objectives. While I believe the code should work just fine, do tell me if the script fails to split, or splits at a wrong position!

Another thing to note about quest objective splits is that you need to actually complete the objective for it to split (or count as completed by the game itself). Slapping Bossling and leaving without the presents is a no-go, for example.

A small sacrifice for saving my Z and X keys

I'm assuming some FlagIDs (which are used for Story splits) are triggered in Arcade as well. I haven't investigated fully what Flags trigger (or what the Active Flags HashSet contains during Arcade), but I don't really need them here, so I added a game mode check for the Flags part. I hope that removes the issue.

Forgot to push to the repository, oof. I've also made the cutscene exclusions on by default, since they're required by the game rules.

Maybe some of the Story Mode flag business is spilling into Arcade splits, so I added an extra gamemode check for that. This is just guessing on my part at the moment, so tell me if you see more extra splitting.

Seems like I also got one of these weird splits at the end of the Sentry fight. I'll look at the code again in case I see anything suspicious.

I'm not really sure why that would happen, since the script remembers which splits have been triggered already.

There's now an Autosplitter for Secrets of Grindea. It can be activated from the "Edit Splits" menu in LiveSplit. Currently, the Autosplitter supports Load Time Removal, Cutscene Time Removal, and Splitting. There's also a Start and Reset option if you wish to use them (check the Settings for more info). I've uploaded a Split List for Story and Arcade Mode in the Resources section. Their names should give you an idea of when a split happens. You can disable splitting for a certain trigger in the Autosplitter's Settings. If you find any bugs or have any improvements in mind (better splits?), you can write a reply here. Note that the use of Autosplitters isn't (yet) allowed by the Mods. Additionally, the Autosplitter currently can't split for the "End of Beta" point.
