linking to an Excell file with SE version 16

[whynojive]

I'm having problems with the stability of files when linked to an Excell document. I can take a model and change dimensions without losing any features. With the same model I can link the same dimensions to an Excell spreadsheet, change them in the same way and have multiple unrelated features fail. When this happens the failed features will have a red exclamation point beside them. When you place the pointer over them they simply say "failed to recompute." I also have problems with the files displaying and updating correctly in SE draft. If nobody else has had these problems, I'll assume I'm stupid. What I really suspect is that the SE programmers are.
