Everything seems to be working fine, as promised here is the mpos patch
Upgrade instructions:

• backup your database in case something goes wrong, shouldn't but it's a good idea!
• stop your cron scripts and wait for them to actually stop!
• patch mpos
• modify database parameters in scripts/sqlchanges.php
• run 'php sqlchanges.php' and wait for it to complete (it may take a while)
• manually run 'cronjobs/findblocks.php' (use -f if necessary - check logs after) and wait for it to finish
• manually run 'cronjobs/proportional_payout.php' (use -f if necessary - check logs after) - if you use a different payment system you can change the code according to the modifications in proportional_payouts.php in the patch, should be relatively simple)
• after the above jobs complete manually do a run of 'cronjobs/run-crons.sh' and wait for it to complete
• re-enable your cron jobs, upgrade finished
