Seemly the way to declare a mod version (using deprecated Mod.Version or the manifest) changed from a string to a struct, this made several mods (like all of mine) to stop working and cause exceptions.

There. Don't bother complaining about this more.
It'll be available to 'use' in the next release build.

If it's too hard to figure out how to copy/paste from the example you can remove the 'Version' line completely and the next time the manifest is read it will be automatically added.
