Since the Arsenal Update, the wrench and ammo icon next to the sundies do not show up on the minimap. This makes it quite hard to figure out as a tanker to figure out where to drive to to resupply, especially on continents like oshur.
4 months later, still an issue. Incidentally, this bug also affects Ammo Dispenser Galaxies and Proximity Repair Galaxies. Sorta hoping they've identified the cause of the bug internally.
