I'm on PC.

I'm level 70+ now and have around 15 settlements.

I've returned to a settlement and it unset the supply line. I think it was because I've visited it.

I'ver tried to set a supply line but it won't let me. It allows to set a supply line only to the furthest settlements.

Usually it would not let me to set a supply line to those far away settlements. Now it is inverse.

Than I've visited another settlement and it happened again. It unset the supply line and can't set again a supply line to a near by settlement.

Is there a quick fix for this ?

Thank you
