I cast Ordeal of Nylea on my Mossborn Hydra, which had 8 counters on it at the time. I then attacked with the Hydra. I got the extra +1/+1 counter from Nylea and then it sacrificed itself, as it should. But the “search your library for 2 lands” effect never triggered. I got no lands. I was relying on that trigger to win the game. Instead I ended up losing on the next turn. So this bug directly led to me losing instead of winning. Stuff like this needs to be investigated and fixed by Wizards ASAP!

Not sure if the Hollowmurk Siege that I had on the battlefield was also somehow involved in the bug. It has a similar effect. But either way, Wizards need to figure this junk out.
