Your comment may be getting marked as spam for some reason. Your best route would be to contact the Patreon support team by leaving a note at patreon.com/faq, they can check and see if the comment was marked as spam for some reason and see if they can restore it.
I am having this problem as well, but their actual contact form is currently crazy hard to find, so here’s the direct link for anyone else who comes after me: https://patreon.zendesk.com/hc/en-us/requests/new
