Hi Daid, I have added a plugin - skip infil. I have tried to reproduce the problem but so far I haven't managed to do that. I am planning to disable the plugin, slice the object, then import the file into a spread sheet using "space" and "." as the delimiter so I can filter by column. That way I should be able to find the error I reported in a large file as I re-enable the plugin's one at a time. I should have some time in the next few days to do this and report back. Thanks
