lately PreciousStones has started purging some fields at startup, and it seems to be mostly new fields.

That's from the server.log after a quick restart, and when the players returned their newly placed fields were disabled.

The player can be online right before the restart and still have their fields purged.

This pops up in the log with regular intervals. I don't know if it's PreciousStones that causes it, but I think so.

2013-05-04 17:41:52 [SEVERE] Error at SQL INSERT Query: java.sql.SQLException: [SQLITE_CORRUPT] The database disk image is malformed ()

What is causing this, and how do i fix it without removing all the fields on the server?

Looks like your SQLite db is corrupted. You may want to google on how to fix that.

Tried that, didn't understand a thing :3

I'm just a regular electrician, not a genius :P
But it seems that the simplest will be to start over again, damn. Ah well, thanks for your help.
