May you try 1.0.3 update?

Seems good now. Thanks!

Just got a different one:

Error while running event advanced_spaceship_repair::on_entity_damaged (ID 114)
advanced_spaceship_repair/repair_ship.lua:58: attempt to index field '?' (a nil value)
stack traceback:
advanced_spaceship_repair/repair_ship.lua:58: in function 'add_to_repair_list'
advanced_spaceship_repair/control.lua:13: in function <advanced_spaceship_repair/control.lua:12>

just pushed 1.0.5. It's likely from the bug introduced from 1.0.4.
