I think this is a known issue with 2.3.4. Try updating to BB 2.3.5 and see if the problem is resolved You could also try downgrading to 2.3.3 if you need to.
Strange. Must be the bug that was present in 2.3.4 still. What font is it? Does it appear in BB Preview?
We’ll have to wait and see what @ZackGriset says. Until then send Support a BBDoc so they have a copy. If you don’t want to wait you could try 2.3.3 if you’re not too far in your game, or maybe even reinstall BB 2.3.5 and update Xcode.
Try to save your file with a new name in 2.3.5. Try to optimize atlases and rebuild. Try to re-add the font as a new font. Try to re-ad the labels or change the font in the label from one to another. This is supposedly fixed in 2.3.5 as stated in the changelog. It was a problem in 2.3.4 though.
Hey, thanks for letting us know about this. If you haven't already, please email support and send in your bbdoc. We will definitely need to look at this one because it was something that should have already been fixed. Yeah, we need to check this out for sure. We will jump on this today and figure it out asap.
Okay awesome man. I talked it over with the team and we are looking into this. It's definitely weird and we will find out what's going on.
