sometimes merge process freezes


Sometimes the merge process freezes. What is the best thing to do. Do we refresh the page, or do we go through the campaign building process again. or do we go back a page and redo it?

It would be nice if the merge process was done by the cron on sending, so you dont have to sit with the browser open and wait for it, and there would be no chance of it freezing.
You can refresh tin case it freezes.

Lots of things would have been nice, i think in the end this entire merging process will be removed for good, seems to bring more issues than it solves.
