Hello everyone,
So I returned to pro recently and was able to use Hoenn's transportation system, not knowing that I even needed to do a quest to unlock it. Anyway I was using it as usual and saw wally standing on the right, so I was like why not talk to him and he challenged me, I won against him but then I was not able to do the quest or even use the system, It teleported me to Wattson in new Mauville, I tried doing the quest from the first step which did not work, and even gave Wattson the final part from Captain Phantom's ship when he was in front of new Mauville's entrance, he finally fixed his system but I'm still unable to use the transportation.
