I always get "The generation of your team is invalid for that tier." but I'm pretty sure my team is seeing I used the same team on Shoddy.

first of all in the teambuilder there is a drop-down tab for the team's tier it is default set to gen 5 but it can be manually changed to any gen 2-5 (and eventually one once rpoject old gens is finished) @FTT if it was just mence he would still be in the ubers tier for gen 4 not stuck in a differnet gen altogether.
Salamence isn't the problem here, although it is indeed banned. In the teambuilder, you have to click "Gen" in the top bar, and then pick 4th gen. Save after that and then it'll be the correct gen.
