Made Mantorite spawn closer to the centre of the depth 3 map. This should stop players from getting stuck on this level with no drillable Mantorite, which is required to gain the next level of drill upgrades. (Won't effect existing saves, due to resource spawning occurring at the time of starting a new game)
Made the PDA log read status get flagged as soon as you see the log, rather than just when you switch to the next log.
