I just found one problem that caused projects of some people to disappear. This is not a new problem and not related to the server downtime these days. So, this problem starts from a bug in the forum (when the person updates his profile, I guess), when certain user ID is written as a "string" instead of "integer" value in the database. Then if this ID is used by the EA builder, certain projects disappear. They are still in the database of course, but the EA builder can't see them. So I wrote 2 scripts and I fixed both databases. Now I will check how this "string" value is entering the database of the EA builder, so I can turn it into "integer".
