Angry Birds Seasons Free/Glitches

This contains a list of bugs and glitches in Angry Birds Seasons Free and Angry Birds Seasons HD Free.

Touchscreen Lock-Up
This happens on both the HD Free and regular free versions.

If you try to view achievements and rankings via the game instead of through Game Center, the touchscreen controls can soft-lock. This can happen with other unknown ways, and there is no known way to fix it other than waiting for it to work.

It is currently untested if you can reinstall the app for it to work again.
