There is a chance that the issue is from something malformed about my json file, but also perhaps the issue happens with any 15x15 crossword?

I've uploaded a sample 15x15 json crossword schema, with no black cells, just for testing purposes. Try opening it up and clicking anywhere on grid on the third row or lower; the app should crash.

Trying to get a surprise birthday crossword done by Tuesday morning, so hopefully I find a fix soon, or else if I'm lucky maybe @gzzo is super active here 🥰

I don't have much details besides there is just no ability to scroll. I will look into this and update this issue with more info.

Hi @gzzo -- this project is an incredible reproduction! But the data format seems pretty tricky. I don't know if the schema you worked out is of your own devising or if it corresponds to some standard format for puzzle data. But I wonder if you know of a way to convert .puz formatted data or it's plain-text precursor into your format. The math seems a little tricky and I'm hoping to not reinvent the wheel.

Thanks!
