Agents are not added to the schedule

[nadaa]

Hi,
I am refactoring code from mesa 1.0.0 to 2.2.4. The simulation uses batch_run and I need to run one type of agent before multiple agents of another type.

I added the following code in to the model:

from mesa.datacollection import DataCollector
from mesa.time import RandomActivationByType

super().__init__() 
self.schedule = RandomActivationByType(self)
self.running = True

then I add agents using :
self.schedule.add(agentx)
It seems the agents are not added to the schedule properly, some agents are skipped!
Any idea on how to solve this?

Thanks
