Process Node Positions Corrupted After Reopening Layout (OneWayPath / One to Many)

Hello, forum users.

I have a question regarding Process Nodes.

I attached nodes to an empty modeling object (roller conveyor).

For this setup, I used the following features:

OneWayPath

One to Many

Initially, everything works correctly. However, after saving and reopening the file, the node positions become corrupted, which then causes simulation errors.

I would like to ask for advice regarding:

the possible cause of this issue

methods to prevent it

The conveyor layout is in a T-shaped configuration.

Unfortunately, I am unable to upload the related files or data. Thank you for your understanding.
