EcoCityCraft’s Server File Cleanup Policy
By using EcoCityCraft's server, you understand that your belongings are subject to the following risks associated with file maintenance:
1. If you have not logged on to the server for 14 days your player.dat file will be cleaned out. This only affects your current inventory on your user, current armor, enderchest contents, and last log out location.
2. If you have not logged on for 7 days, have 1200 or less EcoDollars, and no /sethome locations in your account, you will lose your 1200 EcoDollars. Simply return and vote on all 3 sites to get this back.
3. If you have not logged on for 90 days (3 months), have 24,999 or less EcoDollars as well as 1 home or less in your account, you will lose your 24,999 EcoDollars and your last /sethome location.
4. If you have not logged on for 180 days (6 months), have 24,999 or less EcoDollars as well as any amount of /sethome locations, you will lose your 24,999 EcoDollars and all your /sethome locations.
5. If you have not logged on for 360 days (1 year), have 99,999 or less EcoDollars as well as any amount of /sethome locations, you will lose your 99,999 EcoDollars and all your /sethome locations.
