Hello,
I’m having a problem with localization in Unreal Engine 5 and I can’t find any information about this issue.
My game is basically completed, and localization is one of the last things I need to finish.
My setup
-
Japanese is my native language, and I gathered all text using the Localization Dashboard with Japanese as the native culture.
-
Most of the game is written in Japanese.
-
However, some menu and settings UI elements come from a marketplace plugin I purchased, so those texts are originally in English.
-
I gathered all text together, including Japanese dialogue and English UI/menu text.
The problem
When I open the Translation Editor, all entries appear in the Completed section.
For the English menu/settings texts, I want the Japanese translation field to be empty so that the original English text will be used. To do this, I press the Revert (
) button and clear the translation.
Sometimes this works correctly, but other times I get the following error:
Failed to write localization entries to file
'../../../../../../My Game Project/Content/Localization//ja/.archive'
Strange behavior
The error does not seem to depend on the text itself.
Instead, it happens according to a pattern:
-
I can usually press the
button and clear translations 3–5 times. -
Then the error suddenly appears.
-
After that, some changes stop being saved correctly.
Because of this pattern, I wondered if Revision Control was causing the problem.
What I already tried
-
Disabled Revision Control completely.
-
Restarted Unreal Engine.
-
Removed the Read-Only attribute from all files inside:
My Game Project/Content/Localization -
Tested the game in Standalone mode.
None of these solved the problem.
Additional symptom
In-game localization behaves strangely:
-
Dialogue text changes language correctly in real time.
-
The settings/menu texts do not.
For example:
-
Start the game → Settings menu is in English.
-
Change language to Japanese → Works.
-
Change language back to English → Dialogue changes correctly, but the settings/menu text stays in Japanese and does not return to English.
This makes me think some localization data is failing to save properly.
My question
Has anyone seen this error before?
Could Windows be blocking repeated writes to the .archive file for some reason?
Or is there a known issue with the Localization Dashboard or Translation Editor that could cause this behavior?
Any help would be greatly appreciated. I’ve spent a long time searching and haven’t been able to find any information about this issue.
Thank you.
