Suggested fix (unconfirmed): Restart your game and avoid recruiting Marina at the mayor's house unless you are playing as Levi. Alternatively, download the RPG Maker MV Cheat Menu Plugin, locate the specific tower door switch, and set it to true to progress without waiting.
Suggested fix (unconfirmed): Stop progressing and focus on leveling your buildings with gear that does not require materials to build. Equip your characters with the highest tier gear available before continuing to quest.
I think the easiest is the Iron Creed camp south of Jacob's farm and up the hill. Just bait the soldiers away and then run back to collect the female slave.
Suggested fix (unconfirmed): Backup and restore the `save_0` and `save_1` files located in `appdata/locallow/tophouse/femboy futa house` (or `save_10` and `save_11` for the election DLC) after exiting to the main menu.
Suggested fix (unconfirmed): Use the flower during the fight against monsters with Bella and the brown woman. Alternatively, follow the linked Steam guide for step-by-step instructions.
No confirmed fix yet. Players suggest: I disabled Steam Cloud both per game and globally and nuked the game's root folder from both AppData and fully deleted the game entirely (manually, I deleted the folder from within steamapps to ensure that there were…
Suggested fix (unconfirmed): Ensure you have completed all standard sex scenes and reached the game's progression point where the girls can get "heat" (high desire). Build a girl's max desire the day before, and visit the church in the evening on her designated days (Kasumi Mon/Tue, Ayano Wed/Thu, Shizuku Fri/Sat).
No confirmed fix yet. Players suggest: \SteamLibrary\steamapps\common\Mad Island\Mad Island_Data\StreamingAssets\XML ] - Set [ <buildBlock>1</buildBlock> ] from 1 to 0 - Now you can place any items in areas where you cannot build.
No confirmed fix yet. Players suggest: I just use the Mad Island Uncensor by BarnTheKnee on Github, works better imo cuz it just patches the files instead of running BepinEx which makes the game heavier
Suggested fix (unconfirmed): Rely on natural health regeneration outside of combat based on your auto-recovery skill level, or consume food items to restore health.
Suggested fix (unconfirmed): Verify the game files and restart Steam. If that fails, manually install or check the DLC checkbox in the game's Steam properties.
Suggested fix (unconfirmed): Access the DLC via the "Extra Scenes" link on the right side of the main menu. If you are on Mac and the link fails to open, verify game file integrity through Steam.
Suggested fix (unconfirmed): Start a new game to change the scenario, as the achievement may require a different playthrough. Keep trying across multiple attempts until it triggers.
Suggested fix (unconfirmed): Press the 'A' key at the exact moment the prompt appears on the screen rather than spamming it. Alternatively, try to bypass the climbing section entirely by jumping around the rocks.
Suggested fix (unconfirmed): Use the top-screen labels to guide your search for the notes. For the 5th note, look on the ledge above the entrance doorway in the large chamber with the second Nymph under "The Liberation of the Nymph."
