I have! But they are only stage 1 so far. (I just evolved one to stage 2 but I haven't collected from it since then.) I'm waiting for the collection times to roll around for them again. Then next time I collect I will do a before-and-after on my Orc Warrior count and verify whether it's actually giving Orc Warriors when it shouldn't be. (I also have one unplaced bear in another city that I could place and see if it gives Orc Warriors only when placed, for some reason...)Have you placed a Brown Bear in the current event?
