I tried the 1.4 beta and immediately stumbled upon a Wilding Hermit that summoned a Wilding Rider. Unfortunately the summoned unit misses the warg it is supposed to be riding on and it appears to be stuck in the ground. It can actually move and it tries to attack but it never seems to hit the target. I cross-checked with another unit that has a new summoning ability and fought a Haunter. His summoning worked fine and the Plaguestalker was able to move and attack normally.
