using vines to descend no longer produces grappling hooks

[Kamejeir]

Summary

None

Purpose of change

buggy behavior

Describe the solution

add flags to mutations, check for said mutation on the thing where stair go down but no stair up

Describe alternatives you've considered

Testing

I now see a "Vine leading up"

Additional context

You can't actually redeploy vines, so technically a nerf

Also normal long ropes still transmute into grappling hooks via using them to descend stairs, but that's outside of what I intend to fix here.

Testing was insufficient, I have some more work to do. Testing was sufficient. I just didn't realize that Web Diver required activation.

As I recall from my work on climbing aids, the deployed grappling hook is currently represented by a "long rope" furniture which is displayed as a grappling hook. These two ought to be properly disentangled from one another but the migration might be messy. Be sure to visit the climbing aids JSON file if you look into this; definitions there control what furniture gets deployed when descending.
