Can you describe the bug in more detail? At what exact moment and how does it work?
We will try to track it down and fix it. It is best to do it in Discord in the appropriate channel : https://discord.gg/bXapdyy7
Well, put simply, I tried doing side stuff before actually trying to progress the main story quest on my first save file.
First I bought the meat from the merchant lady, then did the fishing side quest, fishing three times until it was night, went to bed, then turned it in the next morning. Next, did the dwarf cuisine quest, had another quest pop up about a festival, then at night got a scene about the lord's daughter arriving. By this point I still hadn't actually made the food for Lifa, much less turned it in. Next morning, got the scene about the debt.
Figured something about that was wrong, I started a new file. Bought the meat from the merchant again, visited the smithy to trigger the start of the dwarf cuisine quest, went to the fisherman, fished three times, went to bed, then got the debt scene again, again without actually cooking the food for Lifa or encountering her.
