- setting the "variate islands" modsetting to "all" can result in endless world generation, because the game code can not handle it quite well to make everything an island. So better set it to the second highest value, if you want alot of island.
- if the worldgeneration takes long although you set islands to low/none, try to lower the teleportato placement settings on the bottom of modsettings.

- when using the "world settings picker" mod from Zarklord AND have caves enabled, the worldsettings picker will show wrong worldsettings after the first start of the world. I found no way to fix this, but everything else seems to work fine.
