I’m currently working to fix some bugs in my plugins as I have just upgraded to the test-passed version of Discourse. I am currently getting this error which prevent topic threads from loading:
`Uncaught Error: Assertion Failed: A helper named 'cloaked-collection' could not be found`
I have not seen anything that cloaked.js has been removed. Thoughts, suggestions?

I am pretty sure we removed cloaked collection, where are you using it?
did you do `rm -fr tmp/cache`

Thanks, that’s all I needed to know! 😌
