I am using the latest published snapshots but not svn.
When completing silver seed expansion, if you die to the three hags after getting the seed, you respawn back at the keep and can go back down there and finish killing them. This is normal...
After killing them and getting their keys, you proceed and the monk gives you a speech (which on the side topic... wtf). If you talk to the monk before planting the seed, he normally gives you a set of options with a normal bye/etc. If you died as previously noted, he gives you the "return" option (leave monk isle I think it is, I don't have it in front of me) as if he just resurrected you himself. Selecting it returns you to some random spot back in the "future" serpent isle .
