Cruiser AI Occassionally Stops Responding
« on: February 05, 2017, 01:31:21 PM »

Sometimes, the AI of certain ships will stop responding. This results in the ship drifting off in a single direction, and it no longer turns or responds to orders. The ship usually breaks out of this state when an enemy enters within range, or when player control is transferred to the ship. (The ship will do the bare minimum course correction to avoid the edge of the map, however.) This has so far only been noticed on cruisers.

I ran into the bug during some personal testing for the AI tournament, twice with a Blackrock Nevermore and once with a Blackrock Stenos. I'll see if I can find the conditions I used, but the loss of control happened maybe 20-25% of the times the mission was run.

The condition popped up several times during the third round of the Starsector AI tournament, perhaps due to the number of cruisers added to various fleets. Most footage comes from Nemo's twitch stream(Click Here for the video).

Time RangeDescription
48:25-49:00The Shouren (Eagle-shaped cruiser) in the bottom-right corner bounces idly against the edge of the map instead of engaging the enemy fleet.
50:46-51:22The same Shouren continues bouncing off the right edge of the map.
53:20-54:00Despite the enemy fleet consisting of a single 0% CR frigate, the Shouren continues bouncing off the edge of the map. Unknown if it engaged at the end and finished off the Robberfly with a beam.
2:11:30-2:13:34The two Threshers (wide, cyan-colored cruisers) completely ignore the Enforcer behind them.
2:33:00-2:34:45The Haze (unshielded red-colored Diable cruiser) doesn't move towards the battle for this time frame. A Search and Destroy order is issued by the fleet, letting its escorts return to battle, but the Haze doesn't respond to that either.
2:48:20-2:52:15The Thresher on the right, in the nebula, does not engage for the majority of this time. At 2:49:40 it engages combat long enough to kill a carrier and overload the Versant, and then resumes drifting away form combat unresponsively. At 2:50:25, the Haze on the left doesn't respond for about 20 seconds before re-engaging.

Took a look - that does indeed look wrong, but I'm fairly sure it's mod-related. Haven't seen anything even remotely similar in vanilla, and I've run a *ton* of many vs many AI vs AI battles - both recently and just in general.

Yeah, just realized that the tournament code is likely the correlating factor. Sorry about that.

No worries - I mean, it could be a vanilla issue, just seems unlikely at the moment, but good for me to be aware of it in any case.
