This bug was closed and I wasn't sure about the etiquette for trying to re-open them, so I will just post the evidence here.
The attached saved game has me standing on the tile in question. It says I need triple jump but I can pass it just fine with double jump.
The closure reason was "Not actually, your character probably had some sort of jump boost that helped them. But, now that those are gone, this should be less of an issue. ".
However:
- This is still happening under the new version.
- I don't have any jump related perks active.
- I don't have any equipment active at all.
