That is a very generous offer, but as I've generally been knocking out ten puzzles a day as part of my gaming routine (it's like brain exercise, but fun!) if I don't get completely stuck near the end I have about five days left before I finish the full three hundred. Given how close I am to the finish I'd rather not put it on hold for an indefinite period of time, and I'm sure you'd rather potentially take on that level of rewrite without any additional bits of pressure as small as they might be.
That said, if you do get around to that level of rewrite and are curious if this particular crashing issue is resolved or not feel free to reach out to me as I'd be willing to go run into a wall repeatedly for a few minutes to check :)
