I've come across a couple bugs with v5.0.
The mask faceless pointed out above is showing up on several costumes, in some cases breaking the sleeve. i.e. Grimey's maid costume.
Adding mods after loading the character is working great now for static hairs, but is still replacing dynamic hairs with sd chan's hair, as well as cutting off all of the clickable sections of the hair. With the game's static characters it doesn't replace the hair, just cuts off the clickable sections.
I'm not seeing the reset and load buttons in the modder for positions.
The character packager doesn't seem to be properly loading character codes for me, i.e. girls with static game clothing are loading naked. I also have a question, is it not currently supporting multiple mods? The only files it loads are the ones named char.swf, mod.swf, etc. Though it shows the other ones in the saving list and by the file size I would think it saved them (within a few bytes of the original character folder.)
Assuming you're going to continue with the packager I would like to see BG.png saving added to it.
Sorry to be a pita.
