The infamous camera lock bug
Repost from PBE for increased visibility
Recurrence rate about 70% Reproduction steps:
- Start game as any champ in summoners rift
- Use your cursor to move the camera on the minimap
- While moving the camera press "Y" and use the "G" key to ping a particular area on the minimap
- Use "Y" to attempt to relock your camera only to have it not do so.
Quickfix: move the camera using your cursor on the minimap and tap "Y" to relock your screen.
Conclusion: I've run into this bug several times on both live and PBE and it has become a very annoying part of playing League in tense situations. I'm beginning to think it has something to do with pinging on the minimap after using "Y" to take off screen lock.
