i'm not sure if this has been reported already but if you buy a Scaldis at Shady Vault it is been build without mining lasers as you can not even add them to the ship at the equip screen.
If you buy the same ship at the new Shipyard in Gemstone Manufactory the mining lasers are added to the ship automaticaly even if not selectable in the equipment screen.
i have been able to reproduce this "bug" multiple times. So if you want a Scaldis for mining you better buy it at Gemstone Manufactory.

Edit:
at 1.24 - Hotfix 1 The mining laser seems to just vanish from the ships after a certain time of gameplay or once the first order is given to the Captain. It seems that upon loading a save the mining lasers are gone as well.
