Hello! 

Upon reaching the point where you first squash the chest in "blocking your animation", I've discovered that the bottom of my lid doesn't seem to follow the top of the base.

Moving just the base_squash_top doesn't pull the bottom of the lid with it, like it does in your example file.

I've spent quite a bit of time scanning through the previous videos, studying your diagram, re-parenting, and triple-checking my constraints. 

Totally hit a wall here. :|  I have a funny feeling it's something simple somewhere, and I'm tempted to just use the example file to finish the course, but I want to know what I missed so it doesn't shut me down in the future! 

Any assistance is greatly appreciated. Thank you so much!

Hey,

I'm having problems with saving my current progress (error-message below). There seem to be some files missing for the gem. I downloaded the first file at the start of this course. Inside the gem-folder there is only a gem.blend file. But as far as I can see there also need to be other png files.   I don't know if MACHIN3Tools is just messing things up around here, but I don't think it will create those file links out of nothing. For other viewers you might want to check and update the source-file.

Also the gem is still called "Cylinder" in that version. 

With this course being part of the 'beginner' series - the lack of key cast (so you can see what shortcuts/options are being used) isn't helpful. Also, you explain how to do something but there is little explanation of why (unlike previous beginner courses). So if I ever want to rig and animate something other than this chest, I don't know what I should be doing/adding because I've not been told why you're adding certain things or why you've put them where you have and things to consider. Sorry to be critical but it's important for me to understand the theory and the 'why' things are being done rather than just following along for this one example but then being completely stuck when I try to do my own project - perhaps there are some other courses that may further my understanding?
