I think there might be a bug in the latest pxt-blockly release or it might be something I am doing.  
When I import the compressed files, this is what I get ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/20909e50b945be1ec87fbbdcfc937aeca7bcdc80.png)

Hopefully someone can point me to a fix

we’ve recently updated to the latest version of Blockly with their “Zelos” rendering, so you may want to check their release notes: [https://github.com/google/blockly/releases/tag/3.20200123.0](https://github.com/google/blockly/releases/tag/3.20200123.0)

additionally, make sure you’re passing `renderer: "pxt"` in the options for any calls to `Blockly.inject()`
