There was a bug where you weren’t allowed to save your load out before an encounter and then equip the same load out after an encounter. So instead, I would have to select everything one by one, which can be a little annoying. Has this bug been dealt with?
Then you most likely have “Lone Wolf Mode” on. Having this on does make leveling up faster and easier but it’s also more difficult than solo’s since you’re of course going against teams up to 3. But it’s very easy to toggle it off just press “Y” when selecting a map or “Triangle” if you play PlayStation.
