Please watch the screen capture attached to see an issue with hidden columns. If I hide a column which contains a formula, the adjacent column begins to update with the formula results.
In my test, I set A5=1, B5=2, C5=A5+B5, D5=C5. Then, I hid column C. Now, if I modify A5, the value for B5 changes, even though B5 does NOT contain a formula!

I see similar related issues when I load a file (from JSON) which has hidden columns with formulas. The related formulas don't work until I unhide the column. I suspect the two issues are related.
