Can a warp point close by itself as a naturally occuring event? First time encountering something like this and the WP that got closed happened to be part of the main supply route for one of my fleets. If it was NOT natural and one of the AI did this, then it was real clever.
Now the fleet is cut off and I can't get my troop replacements through. Looks like I have to resort to genocide instead of ground assualts... its fault or not the AI asked for it!!
