So I looking through the Bible on Wattpad. And I came across something, weird.

This comment somehow has "-1" comments. How do you have negative comments? SOMEONE EXPLAIN!

So then I clicked on the replies and it gave me this outrageous number.
18,446,744,073,709,551,615
Whateven is this number?
When I clicked it I couldn't read or see a single comment. I couldn't even add a reply. What is wrong with Wattpad?
