Many players discovered something terrible after downloading Subnautica’s August 2025 update. Their favorite mods stopped working completely. Players who spent hours building perfect modded saves found themselves staring at broken games. The Subnautica Map mod wouldn’t show anything. Cyclops Docking stopped functioning. Even simple decoration mods crashed.
One frustrated player summed up the situation perfectly: “Broke everything almost like v2.0 all over again. Guess I need to find something else to play for a month or three until stuff gets fixed”.

What Caused This Massive Problem?
Unknown Worlds Entertainment decided to modernize their game systems. They switched from old Unity input controls to brand new ones. This change brought better controller support and improved performance. However, this upgrade pulled the rug out from under mod creators. Popular mods like these stopped working completely:
- Subnautica Map mod
- Cyclops Docking mod
- Moonpool Vehicle Repair mod
- Defabricator mod
- Various decoration and inventory mods
The technical changes affected any mod that touched the game’s inventory system, used custom sprites, or added movement modifications.
How Can You Fix Your Broken Modded Game Right Now?
The good news is that smart players found a simple solution. You can roll your game back to an older version that works perfectly with your mods.
Step-by-Step Instructions to Get Your Mods Working Again:
- Open your Steam Library
- Right-click on Subnautica in your game list
- Click “Properties” from the menu that appears
- Navigate to the “Betas” tab in the Properties window
- Select “2023_march” from the dropdown menu
- Wait for Steam to download the older game version
- Launch Subnautica – your mods should work perfectly again
This rollback method has been tested and confirmed by dozens of players across Reddit and Steam forums. One grateful player reported: “Fixed my boyfriend’s game. Thank you”.
What About Other Game Platforms?
This rollback solution only works for Steam users. Players using Epic Games Store unfortunately don’t have the same rollback options available.
Some Epic users suggested adding Subnautica as a “non-Steam game” to their Steam library to manage it through Steam’s beta system, though this workaround hasn’t been widely tested.
What Should You Expect Moving Forward?
This rollback is a temporary fix. Eventually, mod creators will need to update their mods to work with the new August 2025 version.
Some mods like these still work fine with the new update:
- Harvest Seeds mod
- Blueprint Search Bar
- Prawn Toggleable Drill Arm
But most inventory-related and graphics mods remain broken until developers update them.
Important Things to Remember
- Back up your save files before making any changes
- The rollback works immediately – no waiting required
- Your modded saves will load perfectly with the March 2023 version
- This is a proven solution used successfully by hundreds of players
The underwater world of Planet 4546B awaits your return. Don’t let a broken update keep you from exploring those alien depths with your favorite enhancements. Use this rollback method to get back to the modded Subnautica experience you love.
