Bleh,
Some say that they still can get em to stack after that last patch.
I am not getting egg bombs to stack at all yet again like they used to be.
That why I stuck on 10 singles packs, too item intense, even the vendor doesn't like holding many, single egg bombs packs.
I think when they dev. the egg incubator, it made the egg bombs ...bomb.
This does not affect smoke bombs though..they stacking nicely as always.
We all had stacks on our vendors as Aislin said and in our homes for restocking...and poof the multi stacked eggbombs became ONE egg bomb.
