EDIT Now you can select a random delay by using RANDOM RUN: {number}
example:

-" RANDOM RUN: 1"
- DELAY 4
- DELAY 5
- DELAY 6
- DELAY 7
- DELAY 8
- DELAY 9
- RANDOM END

EDIT Big improvement of the command /ei create , now you can import all stored informations of the item that you held. (nbt tags, attributes, enchants, name, ....)
I know that some of you use Ultimate Core so now you can give you an item of UltimateCore do /ei create {your_id} and the ExecutableItems will have the attributes of UltimateCore.

New option cancelEventIfNotDetailedBlocks to cancel event if the detailedBlocks option is not validate
