There are no maps anymore. In the new update the default Blockland location was changed from Program Files to Documents. You may need to copy your config and add-on folders over to get everything back to normal.
Maybe it's deleting stuff because I have too many add-ons (I have like about 2000 add-ons)
It shouldn't be deleting anything. It will disable add-ons though if you go over the datablock limit which is ~4000.
