Fritz, I managed to replicate the crash you describe. Mine occurs whenever one approaches the fortress out of travel mode - my guess is it has something to do with the raw size of the fort and the amount of exposed space and other items. In this case, there isn't any point in restarting the fort from a previous save - the 185 save is the earliest one I can find, so if it's already crashing in adventure mode, the problem isn't something that can be avoided. I can't do anything about it except extend my sincerest apologies.
Their may be merchant related bugs, but i realy realy doubt toady will have a problem spotting those and looking at all the tohers that have cropped up.
I can say this as programmer: crashing after editing with third party cheating utilities is not a bug.
The crash described by Fritz occurs in a save from well before I decided to edit the fort with Runesmith. Obviously I can't verify the nature of the abandon crash that the current save is experiencing - I have my suspicions, but it's pointless to pursue the issue further.
Also, while I understand that your intent was probably not to call me a cheater, I feel obliged to point out something about the nature of the fortress. After the initial infertility curse, I dedicated myself to recording the slow and inevitable fall of Weatherwires, in as much detail as I felt was necessary to entertain an audience. In this sense, I was no longer concerned with winning or losing. Tampering with the game using Runesmith, an act which would undeniably be cheating if I were challenging myself in the context of the game, thus became permissible because it was done solely to enhance the story.
That those actions may have irrevocably ruined the save is now a moot point to discuss, since the fort would not be explorable in adventure mode anyway. Coincidentally, in that same save, attempting to reclaim the fortress results in a crash as well. The only reason why, in this situation, the 234 abandon crash might be a real issue is that the new version of legends mode cannot be viewed - and yet, I think that this thread itself serves enough as a record of the events that took place after 185, so even that is not a huge loss.
The save from 185 is still bugged in a few ways - the infertility issue is but one of them. For the sake of avoiding issues caused by third party utilities, it will be the 185 fortress that I will submit, and I will only report bugs present in that save.
As far as the current story goes - I am currently in the process of working on a believable and satisfying ending to the saga.
That, however, will not be the end for Weatherwires - though it might seem as such from the point of view of anyone who is reading this thread. From the beginning, I had intended the fortress to be explored by a third party - ideally, other players in adventure or reclaim mode. Now it is clear that such exploration will not be a reality. However, I have struck upon an idea which will allow other people to explore Weatherwires as well as enabling me to continue the narration. I won't reveal more details than that, however, until after the saga is complete.
