The fixes are in the Scoria thread at TFW. You will probably have to sift through a few pages of people whinging and trying to make the QC issues into something worse than they actually are, but that's par for the course with that place
Everything tabs together fine on mine, it's just one of those TF's where everything has to be just right. It took me about 5 minutes of jiggling other pieces before there was a satisfying CLICK! and everything went in.
I'm torn on whether to put an Autobot logo on the dino head as I like how it looks as it is but I'll put one in the relevant spot on the robot mode, I don't really like putting other stickers on Masterpieces but that's just an individual choice.
In terms of how the transformation works and the aesthetic of both modes I'm more than happy with how Scoria has turned out. It's a lot more complex than Quakewave and has a lot more paint apps so it's easy to see why the QC issues have occurred as there was more potential areas for things to go wrong.
The tightness of the joints on the future releases is something that will have to be looked at and the weight distribution round the hips may need some rethinking as well but I'm still hugely looking forward to the rest of their Dinobots.
