I have a login flow where I set the boolean loginflow_forcelogout to true and yet instead of being logged out the user is logged into the community. This is pretty much the opposite of what I'd like to have happen. How do I get this feature to work properly?

I'm writing a flow to query a custom object and assign new values to update to the User object and I keep getting an error that says "number of iterations exceeded". I made sure to put my lookup and update outside of the loop but it doesn't seem to matter. The initial lookup returns about 1800 records but if I limit the lookup to 40 or so records, it does seem to work. Is there anyway I can modify the flow so it doesn't throw the iteration error? A partial error log and a screencap of my flow are below. Thanks!

LiveOak__User__c Is null false
Assign those records to {!coll_AccountOwnerWithUser}.

Iteration: 0
Current value of {!single_AccountOwner}: a2AG000000hAbrnMAC

ASSIGNMENT: Assign_ID_to_Single_User_Record
