TERRAIN SAVING ISSUE has been fixed.

Terrain saving issue has been fixed.

Based on feedback from Discord,
I discovered that after the last update,
there was an issue where game chunks could not be saved..

This was caused by the use of asynchronous saving for performance optimization,
which led to potential thread conflicts...

The issue has now been resolved.

If you encountered this problem,
I sincerely apologize.
The game can now save and load properly without any issues.
Really sorry about this issue...

If you have any further feedback or suggestions,
please feel free to contact the developer via email or Discord.

Patch 7.2.2. TimeZone Error Fixed. Fishing Error Fixed.

Update Overview:

Fixed timezone errors that occurred in various languages and regions.
Fixed an issue where fishing rod couldn’t be cast.
Fixed an issue where the mouse would disappear when using a controller.
Updated the descriptions for some weapon entries.
Increased the damage of the laser cannon item.
Significantly increased the durability of melee weapon attachments.


Thanks to players from regions such as Poland and France for sending detailed feedback via email.
I have finally pinpointed the timezone issue...
It was caused by differences in string formatting across different regions.

If you encountered any timezone issues before (e.g., flashlight not illuminating the scene),
they should now be resolved.

Sorry for the inconvenience caused to some players...
I truly believe this time the issue has been fixed...

This issue was caused by a string formatting error.
To avoid corrupted strings in previous save files,
it is recommended that players who encountered region format errors
start a new save file to continue playing.

The lag issue caused by the physics system fixed

After the last update,
we received some feedback regarding abnormal lag in the game.
With the help of the player community,
I was able to get the save file that triggered the lag
and conducted an urgent investigation.

I found that the issue was caused by the character's physics system settings.
However, in the last update, I only modified the vehicle physics system
and did not make any changes to the character physics.
This issue may have been caused by a bug in the game engine that altered my settings.

After identifying the problem,
I immediately implemented the necessary fix.
The latest version should no longer experience this abnormal lag.

I apologize for the inconvenience caused. As the developer, I truly regret this issue.
Every major update has the potential to introduce new problems,
but most of them are quickly resolved.

If you encounter any new issues,
please package your game save file into a ZIP file
and send it to my email.
cheshendog@gmail.com
I will respond and address the issue as soon as possible.

The game save folder is located at:
C:\Users\YourUsername\AppData\LocalLow\LevenLiu\ZEDZONE

Thanks again for your patience and feedback.
Thank you :)
