Was your issue resolved? If not please DM or send an e-mail to support. We use lots of servers and Tor circuits sometimes break creating delays, if these issues are more common lately we will make some improvements so it doesn't happen anymore, or at least not this often. Also our clearnet version has been DDoSd continuously for more than 10 days now so that's why it throws errors sometimes.
Problem solved, after contacting the OP, the deposit was safely delivered to my mixer address.
