Does the Navmesh have a limit to how many actors it can handle?

Hello everyone,
I am building a mall and want to have a very large number of people milling about. The problem is I have my spawners set to bring in 200 people and after about 50 or so the characters that are being spawned in wont leave the spawn point. Everyone else runs just fine and through debugging I can see that the AI that are at the spawn point show that their moves are successful despite never actually moving. So is there a limit to how many moving characters the Navmesh can handle? If so how can I elevate that number?

Thank you all in advance!
