Not sure if this is supposed to happen, but since i was not expecting it at all, i found it extremely frustrating.
So i have a spreadsheet that is using several index/match formulas on different columns to pull information from other spreadsheets.
But today, one of the Admins on another spreadsheet made me aware that he was going to add some old records that were needed.
These old records must be found using different references, so i have to edit the index/match formula on those specific rows.
What happened was that, by editing just one formula on one cell, and going back a forth between spreadsheets while doing it, i noticed that the formula applied to that column was completely edited, and its now obsolete. (Note: when i first typed it, was just in one cell, and then expanded it to all the others)
It's not a big hassle, but is this supposed to happen?
