Automations rate limited? Skipping steps?

so we have a board that we use for checklists on product rollouts. each time we rollout a product certain things need to be done at each stage of the rollout and weve been using Monday create subitem automations to help us.

Ive started to notice that it is skipping steps randomly when we move groups of items from one step to the other.
Each task is numbered ( we increment by 10) and I’m seeing missing tasks spread out.

is there a log I can see to verify that each automation is completing all its create subtasks?
why would an automation just skip one of its steps but run the others?
is there a limit to the number of automations I can run at a time?
