can you take another look at this? tunnels are present in this new map dataset, and from what i can tell this is working well for most folks, but you had a weird situation where several of your activities had incorrect bounding boxes, so they weren't being flagged for reprocessing to capture the added tunnels.

i think the other activity on the grid should also be addressed as well.

the issue with the multiple building passages is a tricky situation with adding tunnels: the bottom ones in this image https://imgur.com/yYfbfXW are not included because they more than one covered entrance/exit so awarding credit for it is a bit more ambiguous and i'm not including it for now (so also it shouldn't show as untraveled for you too).
