sometimes to save time when im working with PNG’s, i place multiple items in one png and break it apart for animation  
99% of the time this works fine, but every now and then i find that a few of the tweens or mc’s or whatever randomly turn into red squares - the bitmap fill has been replaced with just solid red and its unrecoverable

has anyone experienced this and figured out the cause?
