Account deletion - Stopping midway

I have recently tried to delete one of my accounts https://kiwifarms.cc/icameheretoawoo it logged me out and started the usual deletion process but then stopped at 1803 posts. I then found that I was able to log back into and tried deleting it again this time with it stopping at 533.

The account did originally have approx. 10500 posts so that may of had an effect on the first deletion.
