Warp point closing

[CW]

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!!

from events.txt:

Type := Warp Point - Closed
Severity := High
Effect Amount := 1
Message To := System
Num Messages := 1
Message Title 1 :=
Message 1 :=
Picture := WPClosed
Time Till Completion := 5
Num Start Messages := 1
Start Message Title 1 := Warp Point Fluctuation Detected
Start Message 1 := [%WarpPointName] is fluctuating from gravitational shear forces. Our scientists conclude it will collapse within 0.5 years.


I have never seen the AI do that, but if they did, the message would be "a warppoint has been closed in such-and-such-system by unknown forces"

or "...by the whoever empire" if you saw them do it.

[Q]

The AI closes warp points. I have seen this more than once! But usually it is just any warp point and not a really strategically reasonable location.
