Hi, not sure if this is new, or just a me issue, but permalinks seems to have an problem.
I rightclick, Permalink and copy the permalink, so far so good
i.e. https://watabou.github.io/cave-generator/?seed=613247753&tags=huge,varied,chambe...
But when I enter it into a new browser tab, it changes the seed and I get a completely new map.
This means I can't save the permalink for a map I like and reopen it again later, which I assume is the intent, and I'm sure that's how it used to work?
Otherwise great update.
