Troubleshooting
Start with the lowest-risk fixes first: restart the game, confirm Steam is online, verify files, and avoid deleting saves until you have copied them somewhere safe.
Fast Triage
Section titled “Fast Triage”| Problem | Try First | Then Check |
|---|---|---|
| Continue crashes or hangs | Restart Fortune Mill, then verify game files from Steam. | If it repeats on the same save, copy the save before experimenting and check Save Data and Carryover. |
| Window or fullscreen behaves badly | Switch to windowed mode from settings if you can reach the menu. | If you cannot reach settings, restart and test Steam compatibility or display settings. |
| Steam Deck input feels wrong | Try touchscreen, trackpad, and controller mappings. | If one input style works, save that layout before changing Proton settings. |
| Linux launch behaves differently | Try a fresh restart and a different Proton compatibility option. | Keep regular and Lethal saves separate in your head before assuming progress is gone. |
| IdleOn reward does not appear | Finish the run, return to the main menu, and use the crossover prompt. | See IdleOn Pet Redemption for the redemption flow. |
Saving
Section titled “Saving”The game autosaves every 9,000 frames and also saves from settings changes. The regular save is separate from Lethal Mode. See Save Data and Carryover if you need the exact saved systems.
Save Safety
Section titled “Save Safety”- Do not treat Lethal Mode as the same save as your regular run. It uses a separate save path.
- If a crash appears tied to Continue, copy the save before testing fixes.
- If a settings change fixes display or input, let the game save normally before restarting again.
- After regular completion, New Game+ creates a fresh regular setup with the NG+ counter increased.
Windowed Mode
Section titled “Windowed Mode”Windowed mode is a settings option. If the game crashes before you can reach settings, try restarting first, then test compatibility settings from Steam if needed.
Steam Deck and Linux
Section titled “Steam Deck and Linux”If controls feel awkward on Steam Deck or Linux, try touchscreen, trackpad, and controller mappings before assuming the save is broken. If launch behavior changes after an update, test a different Proton compatibility option before clearing data.
The June 9 PDT patch added a MacOS build. If the Mac version opens with odd input, display, or save behavior, try windowed mode, restart Steam, and verify local files before deleting save data.
Crash After Continue
Section titled “Crash After Continue”If the game fails right after Continue or while loading, restart the PC first, then verify files in Steam. If the problem is tied to a specific save, keep a copy of the save before experimenting.
Progression Problems That Are Not Bugs
Section titled “Progression Problems That Are Not Bugs”| Symptom | Likely Explanation | Useful Page |
|---|---|---|
| Next room is suddenly too expensive | Bodyguard bribes are one-million currency gates and become much steeper in New Game+. | Room Unlock Order |
| Normal upgrades feel worse in New Game+ | New Game+ increases upgrade growth pressure, so deep levels get expensive faster. | Upgrade Costs |
| Gacha item looks rare but does not help | Item value depends on your current bottleneck, pedestal slots, passives, and set bonuses. | Gacha Items and Sets |
| Lotto feels manual forever | Accountant Toad and Abacus Frog are the key passive-scaling unlocks. | Lotto Scratch Tickets |
| Darts stops mattering later | Trial Mode, Shadow Realm, and Magic make Darts relevant again after later rooms unlock. | Shadow Realm and Trial Mode |
Performance Checklist
Section titled “Performance Checklist”- Use windowed mode if fullscreen behaves badly on your monitor or handheld setup.
- Lower repeated manual actions by using scratch-size settings, Accountant Toad, Abacus Frog, and room automation.
- Use Auto Scratch at Abacus Frog if manual Lotto scratching is the bottleneck.
- If Darts lag was caused by many gold nuggets, update past the June 3 PDT Auto Scratch patch before tuning settings.
- If Pachi or Gacha feel slow after long sessions, restart the game before assuming a save is corrupted.
- If MacOS input or display behavior feels wrong after the June 9 PDT Mac release, test windowed mode and verify files before clearing data.
- If Linux or Steam Deck input feels wrong, test touchscreen, trackpad, controller mappings, and Proton compatibility before clearing data.
