Can a resource just disappear? I swear, I had a farm on Natural Dyes going on, and I have a reserve of 41 Dye to vouch for it, but now, when I finally built my first mill for the paper production, I notice that my Dye farm is just a simple food farm, and I have no more dye income. I have not been importing dye at any point for sure, I was never at war, the region has never been looted, and the only stranger I see in it is a missionary from neighbouring Ethiopia, talking something about their best imaginary friend. Could he have eaten my entire plantation of Natural Dyes in the process? I'm so confused.

Edit: added a couple of pics
Here, the region even remembers there were Natural Dyes, though their income is now 0:
But time passed, and you know what? Dyes came back!
Must be some sort of a bug or smth.

Edit2:
Saved the session, exited to do smth else, came back, loaded the save and puff, dye's gone again:
Definitely a bug.
