Error when placing down blueprints with ammo for the Laser Turret Mk2 7854.972 Error MainLoop.cpp:1468: Exception at tick 22459705: The mod Planet Crucible (0.5.5) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event planet-crucible::on_entity_died (ID 4)
LuaItemStack API call when LuaItemStack was invalid for read.
stack traceback:
[C]: in function 'index'
__planet-crucible/control-helpers.lua:78: in function 'get_lens_insert_plan'
planet-crucible/control-helpers.lua:118: in function 'handle_lens_turret_died'
planet-crucible/control.lua:34: in function <planet-crucible/control.lua:32>

I haven't been able to reproduce this, but there's definitely a missing valid_for_read check in the code where this error occurred. This will be fixed in the next update.
