Angry Birds 2/Glitches

Self-Destroying Buildings
Some levels with the anti-gravity pads could topple over by themselves, basically completing the level without using any bird cards.

Boss Pig Glitch
How-to: Pausing a level while a boss pig is knocked down will shrink smaller, looking like he has no pupils in his eyes.

Miniplayer Glitch
Similar to the "Boss Pig Glitch", the mini player that appears when you pull back the bird on the slingshot has some small glitches associated with it. Mainly the one where the foreground layers don't appear in the top left circle. There also have been sightings of invisible pigs in older versions.

Audio Glitch
This occurs when exiting the daily challenge when completing the first level, then going back to complete the 2nd level. The sound effects and music are silent except the explosions, the card sounds and the damage counter. This also sometimes occurs in the Arena.

Screen Rotate Glitch
Sometimes when opening and closing out of AB2, this glitch could occur that unlocks the game from its horizontal viewing.

Hali-copter Glitch
This glitch occurs with the new version of Hal and when you activate the ability when the purple pig grabs Hal with the grabber gun and at the same time, 2 fans pushing the bird upwards and downwards, which causes this weird glitch to occur.
