[b37] Cannot get back into trollmire

[magikmw]

I've been playing a cronac bulwark, cleared Trollmire, lair of the N bear, and Kol'Pur (something like that).
In Trollmire I've found vaults (that's how you call it? a house with a summoner tree) on lv 2 and 3.
I've decided to skip them, and get back after I get to about lvl 10. I've killed the main trollmire boss as well as the bonus one, and recalled back to main map.

After killing the Shade I went back to trollmire, however that's where the bug has manifested.

On Trollmire 1 the autoexplore didn't work, as well as auto-travel (map click). I single-steped the entire map (the game seemed slooooow), and got to the exit to trollmire 2, where my character lv 8 clone lingered about. When I tried steping on the exit, it teleported me to the next tile. I don't know what could cause it. As I didn't want to walk all by myself to the enterance again, I recalled to the map. Not sure if it has any more effect on the game.

I could provide the save game if you're interested when I get home (in about 8 hours).
