Premiere Pro 2018 has cost me over a week in lost work

I'm editing a feature documentary with an assistant editor on another station.  Since updating to Premiere 2018, issues with conforming media, peak files, inability to import sequences, and duplicated media have cost us more than a week of work.

I want my money back.  You have cost me thousands in downtime.  If the updates are going to cause this much havoc, your programmers should be aware of it and you should warn us.

One other thing--why the hell can't I remove proxies after attaching them?

Many professionals are counting on your software.  These things might not seem like big issues when you have 20 clips in your project file and you're cutting a 3 minute video.  But there are people like me with over 10,000+ pieces of media in a project.

PP 2017 seemed to be working well and I wasn't even getting duplicated media when importing between project files.  Since migrating to 2018, it has been a nightmare.  And I don't think it's feasible to go back at this point.

Get your s*** together, Adobe.
