All the tablets were destroyed in a landslide except one, but that one was also destroyed.
Rough edges everywhere in this game release.For some reason, Lambrecht Forbes now checks whether Oxbay has been captured and if so, tries to link to case "No ships", at which point the dialog breaks because there is no case "No ships". It's not even as if the writer was lazy and simply copied this from "Oweyn McDorey_dialog.c" - there are enough differences that, even if it was originally copied, someone must have adapted it, in which case why leave in the check for "Quest.Story_OxbayCaptured"?
Everything tells me the release was very very rushed.
