Just open PG and start typing  
`Uncaught Error: t._deprecatedCandidates is undefined` on firefox  
`Uncaught Error: Cannot read properties of undefined (reading 'includes')` on chrome

Hey, I’m still getting this error when I type in the playground (also code completion isn’t working). This is happening on Chrome, but with Firefox there are no errors and code completion is working. On Mac, BTW.

```auto
babylon.playground.js:1 Uncaught Error: Cannot read properties of undefined (reading 'includes')

TypeError: Cannot read properties of undefined (reading 'includes')

```

Hard reset of your cache should fix it ?

Thanks, I did a hard/forced reload (with Command-Shift-7) and it’s working now! 👍
