Generic loading in "loading.fla" file
Loading is a bit tricky because it uses a 9-slice which requires some preparation. If you are using sc2fla in Python, then you need to turn all 9slice shapes into fills with a solid fill. Also you need to disable auto kerning in all textfields, otherwise it will not work for some reason. But I have already made all these preparations and am sharing here a fla that you can customize as you want and export.
