Hi everyone,
if someone uses field references, process rules or similar in translations you should verify that the correct ids are used after importing the application in a new environment. Otherwise you may be in for a surprise. The attached image shows that the translated text uses the old variable ids and only the ids in the original text have been updated to match the new environment. I've noticed this in 2021.3.205 for email notification templates and task descriptions.
Razvan from Encorsa confirmed this for 2021.1.4.84 and noticed that you shouldn't use an unsaved field in your translation either. It's negative id won't be updated during save.
An official ticket has already been created.
Best regards,
Daniel
