Hello, I apologize about that. Since 0.18 on Friday there were some complications with the quest database. Essentially, it was discovered upon adding 3 new quests that there was corruption in the quest database. In the process of taking care of it, this ended up being the result. I’m not completely certain, but it seems that any quest given by a signpost has had its progress reset.
This shouldn’t be an issue ever again. The only alternative to this was that all quest progress in your save would be reset. While not perfect this seemed like the better fix. Sorry for the annoyance, at this point quest patching should be stabilized so this won’t happen again.
