Some players report that Custom Farm Types works fine in SMAPI 2.0, but fails in later versions (e.g. see Immersive Farm 2 and its comments). Investigate.

Per mouse on Discord:

• With SMAPI 2.0 (see log), you can create and load custom farms.
• With SMAPI 2.3 (see log), you can load custom farms but not create them. (You can scroll through and select them on the menu, but when you walk outside it will always be the standard farm.)

Reported on Linux (mouse) and Windows (Aquilegia + Kylindra).

Potentially fixed by #424, awaiting confirmation.

Fixed in develop for the upcoming SMAPI 2.4 release. This adds SaveEvents.BeforeCreate and AfterCreate, which Custom Farm Types needs to replace the farm before the first day (see spacechase0/CustomFarmTypes#6).
