Blue orchids, Alliums, and any flower with an ID of red_flower and a metadata value above 0, cannot be composted. Should be a simple fix.

I should add, they cannot be composted by default.

Update, any oredicts added to t he composter via crafttweaker only inserts the first item of the oredict, with metadata 0. I believe the initial issue stems from crafttweaker not adding all the items in the oredict.

Weird...

This could be due to that ItemStacks with metas are stored in the getSubItems() method, but it's never being checked, so only the default item is being added regardless of meta value

I'm not sure if crafttweaker automatically expands the bracket handler into individual ItemStacks or keeps it as requiring a getSubItems call
