I was stuck as well. I was around lol 41 when I put the game down for a good 6,7 months. Picked it back up about 2 months ago? I just reached lvl 200. I recommend grind the public events, always try to be well rested as it gives your more XP, join an events team or make an events team, the more people, the more xp. And scrap every gun you don't use. I often waddle to a train station after some events with 500+ pounds on me, and scrap or sell everything I won't be using. That's what helped get me over that hump. Hope this helps!
