Process queue ignores new list users when requeueing message to list

I have been adding new users to a list everyday and then requeue a message for the new users in that specific list to receive it. This has worked well for a couple of days, i.e. I started with 500 users, sent in batches of 90 per hour. when the batch reaches the limit does not process until next hour (i run it all through crons or even from the ux before cron was set). Over a few hours the queue would clear up and message set to sent. Then add new users and requeue again.

This morning, however, after adding 700 users i have requeued the message and i got the email from my cron that it saw the 700 subscribers left to process but it is not sending any emails. I have requeued a couple of times but it still leaves the 700 users unprocessed and marks the message as sent. I have 3k users and about 2300 emails sent for a specific campaign.

From the events log i see

I removed the blacklisted email (removed it from blacklisting as it is my email and I dont know why it was blacklisted) and retried and saw no different result.

I am only unsure about the message ‘Campaign sending timed out, is past date to process until’ but i would not know how to fix it if the system thinks this campaign cannot be resent anymore.

Also my software details

The version of phpList you are using. - 3.2.5
Your server version of PHP - PHP 5.6.19 (cli) (built: Mar 16 2016 14:21:36)
The url to your installation where possible. (eg: domain.com/lists/admin) - i would prefer not to expose it yet
Which browser (and version) you are using to view your site. - chrome but this is also a CRON problem so it has nothing to do with a browser
What exactly is the issue (screen snapshot can be helpful). - pls see description and if unclear ask more details
What you have done to try to fix the issue so far, including links to any documentation you have followed. - I could not find any documentation that i thought related to this problem. Pls see my description above for the attempts I have made

Ok well, i didnt know some scheduling param existed, ie something was set in the scheduling to block sending of emails for this campaign after a certain date.
I pushed this date to 2 years from now and the queue is working again.
Becareful with your scheduling options
