Can't see the image yet, but if that's the "We don't have x item" message, and it continues the fight, then it's working as intended.
There's certain weapons/armour where you need specific items to make them, and can only get those items from specific monsters in specific places, so the program will keep fighting in those spots until it has the amount of each item it requires. It's just sheer luck on getting the item or not, so it might take longer than at other times.
