Yep, they messed up on the grid. A lot of people (including me. I think my eyes are still bleeding from counting ALL OF THAT STUFF) had the correct answer, but she didn't do that dialogue. Like 2 hours later, they announced they messed up and had to fix something. Then, several minutes later, when you refreshed the page the grid was different.
This is what I did:
First I figured out the total of the center. Doing this would help you figure out how to solve the grid.

Second, get the sum of all the rows and columns that's only missing two numbers. Once you do, subtract that by 175. After this, list all the numbers (in order) that aren't missing *leave a space for the ones that are missing*.
175
- *number you get*

Third, start with the lowest number, like 10. Look at the list and find the possible combination which will equal that number. The only one you'll see is 2,8. So, that's the answer to that one. To make sure this is it, add the numbers all together in that row. If you get 175, you have it! Once you're sure, put something over those places like the number itself or a -. The answers MAY NOT be in the correct space, but that's a different step.

Fourth, continue with the rest of the row/columns from doing the lowest number until ever empty square is filled.

Last, sum up all the columns/rows that were missing 4. If it gets 175, then it's right. If not, you'll have to move some of the numbers around.

As you can see, I messed up and didn't get the sum for two columns. So, I just moved numbers till I got 175. Oh yeah, make sure the numbers are connected somehow. Like see where the 20 is. It's connected to 19, 36 connected to 37, etc etc.

^That's the answer^
I really loved that puzzle the most overall. XD
