How does the Starting inv work exactly I currently have this
startinginv {
# The starting inventory Format: modid:itemid:meta*amt (All parameters required) [default: [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], []]
S:"Starting Inventory" <
[default: [claybucket:claybucket:2],
[claybucket:claybucket:1],
[minecraft:bread]*16]
}
But when I start an island I get:
Error getting starting inventory.\njava.lang.ArrayIndexOutOfBoundsException: 2

Is there something I'm missing? Or a tutorial somewhere or something i could look at?

S:"Starting Inventory" <
claybucket:claybucket:2*1
claybucket:claybucket:1*1
minecraft:bread:0*16

Get rid of [] ,
Make sure you follow the format modid:itemid:meta*amt
All parameters are required

You can also use the in-game mod options for editing the list.
