2nd Team Mission: Gas Station It does not appear to be possible to complete the 2nd objective to "Mine or acquire" 100 Pentaxid (Raw Material). Neither mining by CV, by hand, or by using the really goofy recipe (5 Crushed Stone, 5 Erestrum Ore, 5 Zascosium Ore, 100 Pentaxid (Raw Material)) to produce 105 Pentaxid (Raw Material), satisfies whatever condition is required for this step. Producing 100 Pentaxid Crystals also does not satisfy this step. The 105 Pentaxid (Raw Material) produced by the recipe also seem to have no function, as they do not appear to satisfy the requirements for either Refined or Elemental Pentaxid, rendering them rather useless to produce. Of course, including the material being produced in the recipe is a good bit daft too.
It's a legacy mission. I'll fix it asap. Edit: should be fixed with the next server restart. You have to deactivate the PDA chapter/mission and activate again to apply the fix. And craft the Pentaxid again of course.
