I used to be able to take a straight line and make it wavy with the Effect > Warp > Wave effect - I see that there was a previous 'resolved' ticket on this - it is NOT resolved. I have been using Illustrator for over 25 years and have never seen this app in such a bad state. I am spending more time here today flagging bugs than working on my projects today. I hope you understand how frustrating ALL these bugs are when you are trying to get a project out the door and a client is screaming at you.!!@
