I just gave that a look- it looks like the passability was somehow set to "above player" on the first page of the event.
No idea why that was a thing, but it'll be patched in the next version. I may potentially release a hotfix, too.
EDIT: Argh! The second bounty board later on had the same issue.
I could release the first half of 0.3.5 early to fix this as it's a very glaring mistake, and I've almost finished with said first half. The update will also have some other minor bug fixes- hopefully Burn won't break under certain niche conditions anymore.
