I've been editing verilog with 10.20 for years without seeing this problem. It started for me with 12.20b, and now with 13.00
Sometimes the undo buffer gets zapped, sometimes not.
Sometimes I can clear the problem simply by scrolling to the top of the file, column editing there (with no errors), then scrolling back down to the previous edit area.
Glad to know that the problem is reproducible now.
