Switching languages will not change the language of the next notification

If a player switches languages between notifications, the language of the next notification will not change.

Steps to reproduce:

1. Go to Settings -> General -> Language
2. Import any pack
3. While the first "Import started..." message is still on the screen, switch to another language

Observed result:
The first message successfully changes its language to the newly chosen language, but the second message stays in the previous language.

Expected result:
Both messages change their language to the newly chosen one.

Notes:
This does not happen when importing worlds.
