Part 2 Chapter 5 - way blocked - solved

I'm stuck trying to get to the green portal. Way blocked in the dungeon one end and way blocked topside the other end.

I can see a totem but that's Way blocked as well, as are two bushes on two slopes.

ETA I found the green portal and got an oratory stone. It didn't open anything up though.

I wonder if Way blocked on the bushes to get to the totem is a bug. I ran out of time.

ETA 2 Ok - this is silly me. I played again and noticed the two ramps at right-angles to the bushes this time (once you've done the strength level 5 bush).
