I think I have found a bug on VGC. For games like Final Fantasy X, where the sales were not tracked fully and instead there are just regional totals, on the actual game page, it just appears as 0, despite the values appearing in the search list

Another few VGC questions:
1. Could the totals for the regions be put at the top, because it is very inconvenient having to scroll down through several hundred weeks of sales to find the total
2. Are the software graphs coming back?
