A few of these, mostly the softlocks, have been fixed already in 1.0.4.1/1.0.4.2, but the rest will be fixed in the next patch!
As for the rocks, I was working on expanding the map for 1.1.0 & 1.2 since I worked on other content at the same time as the development for 1.0.4, so I put the rocks there as temporary blockades.
