Description
A meadowlands farm cannot be created. The problem is the function menu.createdNewCharacter(true); or one that follows. An exception is thrown when a new meadowlands farm is created.
I think this is a general problem, but I am using a multiplayer mod. For example, if I create a new farm with Game1.whichFarm = 6; for beach and call the function, a new world is created. This means that all the necessary settings have been made correctly.

To Reproduce
If a new farm is created with Game1.whichFarm = 7; for meadowlands and the function menu.createdNewCharacter(true); is called, an exception is thrown.

Hi! The meadowlands farm is implemented as a custom farm type. Farm type 7 is mod, which requires the Game1.whichModFarm field to be set.

If you need help updating the mod to support it, you can come ask in #making-mods-general on the Stardew Valley Discord. Most people who can help don't watch the SMAPI issues, since they're only for SMAPI development tasks. Feel free to ping me there if you don't get an answer!
