Details

I have a few scripts that download multiple files.
It used to work before. Now it will stop giving me downloads after a bit.
I can introduce a delay, and that seems to work as a workaround.

The problem is all the promises return fulfilled. (E.g. call GM.download x times, get x fulfilled promises.)
But when the browser starts fucking LYING to me, I don't know what to do at that point.

    .then(() => {
