Symbol Set Conversion warning

Recently I received an OCAD 9 map file, imported it into OCAD 2019 then used Symbol Set Conversion function to convert it to OCAD’s setup for ISOM 2017.

While planning a course I noticed that a small cliff symbol was inverted. Further investigation showed that some of the other invertible symbols were the wrong way around. I discussed this with OCAD hq and they have now added a warning to that effect in the OCAD wiki.
