Crash when altering spreadsheet data

We made a visualisation of water flow in a river, using a spread sheet with 12 columns and 930 rows where from data is taken to a matrix with dimensions 365* 30 then draws a polyline for the flow each year.

It works perfectly fine until we try to erase data and fill in data from a different river, then the file crashes.

Any idea why?

Thank you
