VGVN patrol issue

When I put units on patrol, they get a nice red overlay around them. But when I take them off patrol, the red overlay remains.

Any help would be appreciated.

If someone supports the module that person will be best placed to help.

If it’s something that worked in the past then it might be Vassal related.

Can you provide more details about the module ?

Module 4.3.4 but I had this problem with 4.3.4b and with the GMT module.

My opponent does not have this issue while we are playing real time.

Only on my screen.
