How to Fish Troubleshooting Hub

✓ Verified for Patch 1.0.9 · Aug 26, 2026

Every fix guide on the site, grouped by symptom. All of them follow the same rule: reversible Steam and settings checks first — nothing that risks your save before it is backed up.

Before anything else

Back up your save folder before deleting, verifying, or "cleaning" anything.
Restart the game and Steam once — it resolves a surprising share of session bugs.
In co-op, reproduce the problem in a solo session before blaming the game: many "bugs" are host-state desync.
Note your game version (main menu) — advice from a different patch can make things worse.
