Subject: [PATCH] Fix several issues with EntityBreedEvent
|
|
|
|
Upstream did not account for different hands when storing
|
|
the breed item for later use in the event. Also they only
|
|
stored a reference to the stack, not a copy so if the stack
|
|
changed after love mode was started, the breed item in the event
|
|
also changed. Also in several places, the breed item was stored after
|
|
it was decreased by one to consume the item.
