When I writeany world appears Waiting for translation. Which is the problem?

Without more information I cannot do much to help you.

The only thing that I can tell you is to update the factorio library mod.
Since I noticed a while ago that with the latest stable factorio version and not the newest factorio library mod this issue occurs.

If this doesnt help you I need more information from you like:
- Game version
- Factorio Library mod version
- What did you do / see before this happens
In this specific case: Did you see the pop-up which notifies you that translation is happening?
- Maybe even the log file

I was able to track down this issue and the solution is to update the Factorio Library mod .

The reason is that in any Factorio version later than 1.1.74 the translation method the Factorio Library mod uses got changed slightly and causes the translation to get stuck.
