invalid memory address or nil pointer dereference

[K9Sports]

My jfa-go crashes almost daily. I THINK it may have to do with invites but I'm not sure since I cannot duplicate the error. It just pops up when I check it. Has this been addressed before and I just couldn't find it?

There's a message there about the database already being open, and then the crash happens when trying to access app.db, which is nil because the DB couldn't be opened. Is there any way you could be starting two instances of jfa-go simultaneously?

I saw that but I can't find anything on it. I checked all processes and don't see a second jfa-go process running at all. I don't see where there's an automatic loading of the program anywhere. And I run jfa-go (Windows) as Admin. That doesn't help.

This is just so random, it's really hard for me to trouble shoot since I can't re-create the problem. It just happens so hoping someone would have a solution.
