Resource respawn/ reset frequency?

How long does it take for natural resources to respawn/reset given no one is visiting the area? + what are the specific rules/ requirements regarding this?

and how long can you abandon you’re town before it completely resets (everything gone except odd things here and there)

i.e.

The area must not be in your frame for 14 days for resources to respwan

not visiting town for 30 days = reset

can anyone confirm the details?

Thank you :slight_smile:
