Nope just every month or so

A few small ones

The Chainsaw gun in the events shop now has a melee hotkey attached
The Hell, Water, Fire, Ice event items now heal gang members even if you're at full health
The forum identifying system is now based on emails and not IP (I removed it, if you don't register with the same email in game you won't receive the achievement)
The rare lollipop sword now says (Rare) on the trade tables
The Birthday room now displays the hat correctly (free hat)
The Valentine Bomb now uses the old particle system again (was converted to gani for Facebook, but Facebook can now display particles) - visually looks better
Updated the graphics on the 'Fort Killers' event - should I add the other gang areas not just the 3 near the start?
