In one scene I have a BBText with two other elements. A sort of dictionary, if you like, so I click an entry in the previous scene and it changes the BBText according to the variable.
When I use the Preview all the text is displayed correctly, but when I export to .apk in some very long entries it only shows a black rectangle.
I also have a Camera Scrolling System for viewing text off-screen.
In case anyone needs it: I broke the text and created an overlay of BBText objects. Obviously only in a certain condition of the variable. It is not optimized, but it works without increasing the number of variables.
