I don't know if Oasis knows about this already, or if it's really all that known at all by the playerbase since I just realized it earlier, but the Lineup/Set system is causing some weird glitches. Whenever I swap between the three lineups to try out different teams quickly, all of the equipment becomes completely disorganized for no discernible reason. Equipment is randomly placed on different ninjas, as well as magatamas and rune stones. For instance, I stacked up Initiative runes on the Fire Main, but after switching to a different team for a bit and then coming back, all of the Initiative runes got put on a completely different ninja. I reorganized everything afterwards (which took a long time), but when I swapped again later on, it just happened again. None of the equipment, magatama, and rune placement seems to be saved, which really hurts my team since I need certain ninjas to have higher stats in order for my team to work, though really that goes for every player.
For now, I'll just manually swap out my ninjas in just one lineup whenever I want to change up my teams, but I hope this can get looked at and fixed soon.
