Copying 12 categories with 3 subcategories each (no downloads) times out after couple of seconds with:
QuoteError
Another batch operation is still in progress. Please try it later again.

Warning
Batch process failed with following error:
max_execution_time 180 (but I dont feel that limit was hit because that did not happen on jD 1.9)
EDIT: just realised by accidentally looking at the front end the batch is somehow still going on deep in the background executing the copy comand ... should there not be a progress bar indicating the ongoing action instead of an error message?
