Bug or rare event?

I just had a T17 Abomination map that resulted in 315.327 Gold.
every square meter of that map was packed with mobs...I have never seen anything close to that.

map was nothing fancy, just rolled well for me (RF), some ambush scarabs and thats it.

when I entered the map, it looked like delirium fog, but there was no mirror but a wildwood entrance.

was very weird, did anyone experience it as well?

Interesting. I haven't, but have seen some people talking about some pretty big numbers. Maybe a particular mod on the t17.
