AI ships seem to have a very strange reaction to superior forces in the latest 1.12 version.
When confronted by superior attackers, the ships head immediately for the nearest Jump Point, even if that jump point leads directly into the 'enemy' home system. This could, in theory, be good tactics, but they jump through, and find themselves confronted by a large blockade force. Again, this could be the fortune of war.
Now, however, comes the buggy part. Before my ships can open fire at pointblank range, they jump BACK through the jump point, and my ships follow them through.
At this point I assumed they would try to run for it...
In reality, they continue to jump back and forth, with none of my ships, even on 5-second increments, ever able to actually fire on them, on either side of the jump point. I finally was forced to split my forces to sit on both sides of the jump point, in the hopes of engaging them. But they still jumped back and forth without me being able to get a shot off on either side of the gate with the waiting ships. This continued until I gave up and allowed them to leave after 18 cycles of jumping.
This... really isn't good for the game, as it makes it possible for any force, no matter how weak, to avoid engagement indefinitely. I thought there was some sort of jump cooldown which would prevent ships from making another jump instantly, as well as not using sensors? My guess is, since this was a stable jump point, that no jump engines were being used, and thus there was no cooldown. I think there needs to be some sort of basic jump cooldown before another jump is possible, ideally a cooldown which is longer than the jump shock, allowing a chance for ships with superior speed to actually engage their enemies, since they cannot escape.
I know that NPR's don't have the same downsides for jumping as the player, due to weaker decision making, but I cannot think it is intended to be used in this way. In each case here, the ships were jumping back through the point within 5 seconds, with seemingly no end in sight.
