Error: Could not load item data. But ignoring

[Shendare]

I think the 'Checking Database Conversions' step is a point where older database structures (the term 'character blob' was enough to make people pull their hair out) are converted to newer ones.

So, as long as things are working after the conversion step, you should be good there.

Maybe something will come along and put a light bulb over your head on the problem with the first machine.
