Plugin seems to miss some build step / stage

[haffla]

Hi! Thanks for this plugin.

I got this strange output. More than 8 minutes build time. But adding up all stages I don't get anywhere near 8 minutes.

General output time took 8 mins, 48.72 secs

Any clue where the rest of the time could be spend?

Edit: When I remove the terser plugin, build time goes down to 45 seconds.
