Ok, that was fast. I am afraid next time you'll fix a bug before someone even notice it ;)

fixed. Issue #667 is a different one, and I think that issue #670 is invalid... I least I can't reproduce it.

Hm, I just saw 2 other issues that are maybe related (or even the same) 667 and 670. Anyway, I submitted this under new issue 671

I've not tested it yet, but could you open a bug on the issue tracker ? thanks.

I think there is a bug with scale when using zwoptex texture/plist with offsets in combination with CCSpriteSheet (cocos2d 0.9 beta). Here is simple code:

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"testing.plist"];

CCSpriteSheet *sheet = [CCSpriteSheet spriteSheetWithFile:@"testing.png" capacity:10];
[self addChild:sheet];

CCSprite *sprite = [[CCSpriteFrameCache sharedSpriteFrameCache] createSpriteWithFrameName:@"spr1.png"];
sprite.position = ccp(160,240);
[sheet addChild:sprite];

id action1 = [CCScaleTo actionWithDuration:5 scale:0];
[[CCActionManager sharedManager] addAction:action1 target:sprite paused:NO];

Watch the animation and you'll see strange behavior. spr1.png is 320x480 image with most pixels transparent, so when trimmed in Zwoptex, there are offsets. Same code works ok if sprite isn't added to CCSpriteSheet but to scene/layer for example.

I don't think you need actual images to test this, just use any zwoptex texture with offsets...
