Tixx day 3: Mutliple active objectives
It is bugged. You have to do all the other events first (Those of Stop 1, 2 and 3) for the 3rd Toxx event to start, which actually works. After doing all the events (except for the first two toxx pop-ups, which do not work) you get your reward and the chest spawns.
The toy soldier event that start along with the broken turrets event are the last before the 3rd Toxx event.
A fix should be coming in this evening. Sorry for the confusion!
thanks, tired it, and it worked
