Since the 9.10.0 release, I get this error in 11ty when LiquidJS’s cache option is set to true:

Error writing templates: (more in DEBUG output)

> Cannot read property 'prev' of undefined, file:src/_layouts/index.liquid, line:1, col:1

It doesn’t seem to be one single template causing this issue either; commenting out lines has the error appear against other templates. Any clues why this might be happening?
