I saw your post previously and thought it was solved. Sorry about that. Tomorrow when I am in the office I am going to try a migration using XAMPP, 1.6.1.11 to thirty bees and see if I encounter any issues. If so I push some changes to the repo to fix them.
Its really disheartening to hear some I know is a developer having these issues and at the same time not able to debug them. That is what open source is about, helping the community as a whole with bug fixes and making stable software. We are a small team that is trying to bring a software to a stable version. Not a multi-million dollar company that is ignoring your wishes. We want this to be stable. We have a lot of sweat, blood, tears, and our own money invested in it.
We will get your migration working, I am going to look into it personally and make sure it works. But please, don't group us with other software companies that do not have the merchant's best interest at heart. I think that is unfair and I am sure you do as well.
