I've recently started a new playthrough and have only been on the Salzwiesen map so far, for about 20ish hours. I've seen plenty of burrows, but not a single european rabbit at all. The burrows ALWAYS say used recently, yet I've never gotten a warning call or anything of the like. In the beginning I just thought I always scared them before catching a glimpse, but the fact that I haven't gotten a single warning thump in 20 hours of gameplay makes me think that they are simply not spawning. Is this a bug? Has anyone else have this happen to them?
