Computer: 5K 27" iMac, 4.2Ghz i7, 16Gb RAM, Radeon Pro 580.
Build: V26 Experimental version deployed Saturday/Sunday (can't seem that version number as now running 0.0.26.19695 'Bright Night').
I am four hours into a game started on Saturday/Sunday's experimental hot fix then a had a mass wolf attack with loads of nuggets killed, then all of a sudden the nuggets and wolves have become rooted to the spot - the disco stags (Mac feature only) are still moving around. The very recent hot fix (Monday/Tuesday) has since deployed and the save I made on the earlier version loads but the nuggets and wolves are all still frozen.
Save attached, I hope it helps! Loving the game thus far
