Right now, the docs aren't very clear on when existing tables are deleted. Does it happen every time when the option is set, or only if the old table is not structured correctly?

[bonedaddy]

Good point I will update the docs. The tables are only deleted when RecreateTables is set, and the warning is accepted

So if the option is set and waring accepted, then the tables are always recreated on every program start?
