Im not sure where you get the impression there that they were removed. What actually looks to be the case there is that there is an issue with your mysql instance. It is looking to repair tables in which the physical files are not present. After all, if they are not there, why would it be trying to repair them otherwise? There is only your hosting company that can resolve that, and only a restore from backup will correct the issue at this point. Its quite few tables you are missing there
