@Martina K This appears to be several issues, some of which need changes in the Agent module. First, you should make all of your social forces have an "Only When Traveling" active rule. If all of your social forces have this rule, then it will only apply social forces when the objects are actively doing travel tasks. This means that when they are doing other things, like waiting in a line, the social forces will not be applied and the line's update logic will take over. This is a simple solution. If you need it to be more complex, then you should specifically define when forces should be applied and when they shouldn't. This can be done by setting label values on the objects at certain points, and then using the "Label Value" active rule option for each social force.

That said, even when I make this change in your model, it's still not working as it should. This is because the social force logic was defined assuming that all objects are in the main model layer. However, the people module activities move objects into and out of other model objects, like the waiting lines. This messes up the social force behavior assumptions, and causes weird issues where the Agent system thinks they are in the incorrect location. This could be solved if you could make sure the objects are always in the main model layer when they travel, but I've tried this myself and it appears the objects are moved into other objects even when I try to avoid it. So this will need to be a change to the agent module to take these factors into account.
