2022-01-04T08:32:00Z Updated. Game engine v188.8.131.52 used.
First please read FS19 modDesc.xml page.
You can now find modDesc version from v184.108.40.206 game log. Search for "ModDesc Version:" string in the log, the number is the current game engine modDesc version number.
2021-12-24 22:23 ModDesc Version: 63
Keep your modDesc.xml files first line always up to date against game engines version. Obviously this doesn't mean you need to release "re-issue" of your terrain just because new game update increments modDesc Version number, but when ever you are releasing new update make sure modDesc is up to date as well.
