Null reference exception when selecting a table

[Josh]

Hi,

I am getting a null reference exception whenever I click and drag to select a table in a RichTextBoxAdv. This seems to happen most often when you select from the bottom right of the table and drag up and left. It also seems to only happen if the selection contains more than one table. The screenshot I have attached shows the document I am editing and the selection that I have made to cause the crash.

Please see the stacktrace here: https://pastebin.com/ztn63aDZ

I am using version 18.1.0.43

Thanks,

Josh

Hi, please find attached the document which is causing the exception. I can reliably reproduce it by clicking the final total and selecting up and left towards the top left of the document.
