Deleting column causes formulas to stop working

[wd_perf]

ParamQuery Pro 8.5.0 and earlier versions, at least since 8.3.0.

Steps to replicate:
1) Go to https://paramquery.com/pro/demos/context_menu
2) Enter a formula in a cell [like "=1+1" in cell A1]
3) Delete the column where the formula was entered [use context menu on cell A1 to delete column]
4) Enter a formula that references another cell [like in cell A1 enter "=D4" and press Enter]

Note, formula does not work and error in console. Cannot get any new formula to work.

Thank you.

Thank you! In the mean time, is there any chance you could provide a patch to fix the issue? I've been trying to fix it myself, but no luck so far.
