I started the last collect 10 event at level 13, and ended it at level 18.
I believe this is because I fat-fingered the "attack" button when going to rob some laundromats to collect the briefcases, and completing the "defeat 1 rival" goal unlocked a cascade of "obtain XX mafia attack/defense" and "reach a mafia size of XX" goals, which I then completed simultaneously, and continued to complete throughout the remainder of the event.
My question is, anyone know of a guide that lists these goals in order and the XP that comes from them?
I ask because my next goal is to obtain 300 mafia, and I worry that there's other goals in there like "expand X# of times" or "build X# of buildings" that, along with the A/D goals, will catapult me above level 25 when I go to purchase my first night club in a few weeks (requires 300 mafia).
So far my only idea to deal with this is to coincide my obtaining 300 mafia for the night club with the start of a boss event, so that I'll still be in tier 1 in the event those goals do put me above lvl 25. However, I'd really rather continue camping for a while and remain in tier 1.
Any help or advice would be greatly appreciated, thanks!!!
