[Throwable Creeper Eggs] Spawn egg duplication issue

It seems ExplodeAny causes some sort of duplication issue when a creeper egg is thrown, see recording.

ExplodeAny configuration:

# Whether to use a database or not. While it's not necessary at all, a database will keep
# track of every block's durability, so durability is not reset after a server restart.
# Warning: the file that contains the database can become huge, so consider cleaning it up
# (this is, removing it) after X server restarts (let's be serious, nobody's gonna care if
# a block he/she damaged three days ago has now its durability fully restored).
UseBlockDatabase: false

# (Note: not used at all if useBlockDatabase is disabled)
# This will perform a database cleanup every time the plugin is reloaded.
# This can help reducing the database size, but may also load the chunks where the blocks were
# located.
CheckBlockDatabaseAtStartup: false

# Maximum and initial durability of every block handled by ExplodeAny.
# [Minimum] is 1.0.
# [Default] is 100.0.
BlockDurability: 100.0

# Metrics allow us to obtain information about the number of servers that use ExplodeAny,
# as well as some of their characteristics, including operating system and Java Version, etc.
# All this data is completely anonymous, and sending metrics does not affect performance. We
# use bstats (https://bstats.org/) to gather all this data.
EnableMetrics: false

# Named groups of materials and/or entitys. You can create groups with a mix of materials
# and entities. When you use the group in a certain section, the plugin will choose only
# the values that make sense for that section. If no value in the group makes sense for the
# section, then it will be considered an invalid group. You can use the name you like for the
# groups, but if group's name coincides with a valid material or entity's name, then the valid
# material or entity will be selected as the target, and not the group.
#
# When a single entity/material appears more than once in the same section, the following rules
# will be used to merge them, depending on the section:
#
# EXPLODING ENTITIES:
# 1. If an entity appears in two or more groups, then the material configurations
#    will try to merge without overwriting each other. If a material configuration
#    for an entity appears in both groups, then the material configuration of the
#    group that appears first in the configuration is applied.
# 2. If an entity appears in two or more groups but also as an individual item,
#    then rule 1 applies, and after that, the individual configuration will be merged,
#    overwriting the previous rules if necessary (has greater priority than groups).
#
# MATERIAL CONFIGURATIONS:
# 1. If a material configuration appears in two or more groups, then only the material
#    configuration of the group that appears first in the configuration will be applied.
# 2. If a material configuration appears in two or more groups but also as an individual
#    item, then the individual configuration will be applied.

            #
            # If replaced, the new explosion will have the specified explosion radius, but some properties
            # of the original explosion might get lost. For example, if the original explosion was to set

# There are four types of cobweb interactions: VANILLA, BOUNCE, DESTROY, EXCLUDE
# The "VANILLA" type will not change the behaviour of thrown eggs touching cobwebs.
# The "BOUNCE" type will make it so that thrown eggs bounce off of cobwebs when touched from the side or the bottom.
# The "DESTROY" type will make it so that thrown eggs are destroyed upon touching a cobweb.
# The "EXCLUDE" type will make it so that the thrown egg explosion does not destroy any cobwebs.

# There are two types of filter-types: INCLUDE, EXCLUDE
# The "EXCLUDE" type will exclude any blocks from exploding that are in the "filtered-blocks" list.
# The "INCLUDE" type will include blocks in the explosion that are in the "filtered-blocks" list, but any
# other block is excluded if not in the "filtered-blocks" list.
