Item got duped when you break the chest

[cupang-afk]

How to produce

1. kill yourself
2. go to your death location
3. break the death chest
4. voila

i have tried this for like 10 more times

other behaviour (open the chest -> take all item -> chest break/disappear automaticaly) work as intended

config:

# The Configuration file of Death Chest
#    In this file you can customize the plugin.
#

# Do not touch this!
