Issues in Assembly Modeling Files & Manual

I've noticed several problems in the 2019 Assembly's course, I will update here with more once the class wraps up

Notable fileset issues using 2019 SP3:

Lesson 01 - Advanced Mate Features:
Cam mate flips improperly most of the time after placing and moving follower or performing rebuild

Workaround: old method of fit spline / continous cam face is stable

Lesson 05 - Mate Controller:
Angle mates flip on themselves if you try to animate, or enter in/out of Mate Controller repeatedly

Workaround: recreate angle mates with reference entity is stable

Notable typos:

p. 211 Bold Step #2 states "Group Component Instances" even though the text below describes "Do not show Configuration/Display state names if only one exists".

p.255 Bold Step #3 states "Select hidden" even though the text below describes "Select Internal Components"

There may be more, I will update if I find any others. I will also submit SRs for these next week after class wraps up
