This takes the change added in Droplet prs 231 and 233 and applies them to our repo. See the PRs for details. The first fixes a for loop parsing bug, and the second fixes a null error.

To apply the changes here, I built the new droplet files using DROPLET_LANGUAGE=javascript grunt dist in the droplet repo, then copied the resulting files from dist to the droplet folder.

I confirmed locally that app lab and game lab still work as expected. I've been unable to repro the actual null exception, but the for loop parsing now works!
