In the original game when two different trainers see me at the same time it triggers a dual battle. In PokeMMO, it triggers two consecutive single battles. I immediately thought it was an engine limitation that couldn't be circumvented, but I googled a bit and found an old Reddit post saying it should actually work like in the actual game and trigger a dual battle.
So what is it then? Is it a thing not supported yet or am I doing something wrong?
Dual Battles work fine with trainers like Twins and such that specifically trigger DBs, but not the "cross sights with two different trainers" thing
