problem

Due fixes in the worker system the event when pre-translation workers were added had to be changed.

For tasks with pre-translation triggered by language resources added by task defaults this was not working since workers were queued before the evaluation of the task defaults.

Indeed it was a coincidence that it was working before, leading to the situation that sometimes it did not work - leading to the worker changes as mentioned at the beginning.

solution 7.20.4

Change order of adding workers and task default evaluation.

solution 7.20.5

Changed another place with the same problem, and fixes needed in Terminologie handling due a follow up error.
