Question about stage B training instabilities

[Lime-Cakes]

I have a question about the Discussion section of the paper. It mentions two issue, the issue of varying image size and the issue of training instabilities. I'd like to know more about the latter issue (and potentially fix the first issue). Can you provide more information on the training instabilities you encounter while training stage B? If you still have the loss chart saved, can you share it (if related to the training instability encountered)?
