Rules question - monster stacking

By Squidders, in Mansions of Madness

Played my first game last night. Other than everyone going insane it was good fun.

However, I have a question about monsters and stacking.

I ended up two two Hunting Horrors spawning. They both ended up with orders to move and attack the same investigator. They have medium sized bases which pretty much fill a Space. Should I have moved them both into the same Space?

I don't see any rules limiting the number of monsters or investigators who can be in a room. Are there any limits?

Thanks,

Steve

As far as i know, there is no limit.

Their bases sometimes make it hard to fit everything, but i think the challenge is fair.
