Android Building drop issue

[chota_chatri]

I am getting all other collection except the "3D glass".
I have that a mission to complete for current event but not a single 3D glass drop came since day one...
I ran with Secret Basement bonus and other bonus as well still no 3D glasses.
Have 3 movie theater and 2 retro theater.

Any guesses for this issue with Airport City?

It happens to all of us from time to time especially since you have so few event buildings. Normally one item in a collection is harder to get. Build 6 of each theater to increase drop chance.
