Event dragon.11 tends to give dragonbone statues

When your dragon dies event dragon.11 is triggered, which gives you an option on what to do with it. One option is to make an artifact.

However, that option tends to give you a dragonbone statue even when it's not supposed to. Here is the "offending" script:

if = {
limit = { has_character_flag = dragonbone_statue }
add_artifact = dragonbone_statue
}
if = {
limit = { has_character_flag = dragonbone_amulet }
add_artifact = dragonbone_statue
}
if = {
limit = { has_character_flag = dragonbone_scepter }
add_artifact = dragonbone_statue
}
if = {
limit = { has_character_flag = dragonbone_seal }
add_artifact = dragonbone_statue
}
if = {
limit = { has_character_flag = dragonbone_necklace }
add_artifact = dragonbone_statue
}

As you can see it will give you a dragonbone statue even when it's supposed to give a dragonbone amulet, scepter, seal, or necklace.
