We have a multisite with JoomSEF 3.9.5 installed. When trying to create custom urls receive this error:
Error Saving URL: Table '518095_mhcint.lcf_sefaliases' doesn't exist SQL=DELETE FROM 'lcf_sefaliases "WHERE 'url = 2762

First, how to resolve?

Second, we've have had other table errors in the past, needing to add additional lines, when installing patches why don't the tables update?
