They appear somewhat too frequent if bigships is installed at least.
That's a more general problem with BigShips. If the BigShip pool does not have enough variety, then you'll see the same ships too often. Liners OXP and Adck's Bulk Haulers OXP help, but IMHO BigShips would need a bit of a tune up. Maybe I'll take a look at it at some point.

Hello. :)

I've used to play Oolite several years ago, but it seems my old aegidian account was lost in space. :) So I registered a new one.

I think I found a bug, maybe not in Dredger OXP itself. But something has changed since I last played the game (v1.76.1, btw).

Recently I installed a new build of Oolite (v1.82) and some of my favourite OXPs (Deep Space Dredger included). Hunted a ship (Trident Executive Shuttle), then shoot it until the pilot escapes and ship became derelict. Launched a salvage missile, followed the auto-piloted ship to the Dredger, got rid of several waves of pirates. But... on the final approach to the Dredger, the shuttle suddenly stopped, turned off the engine and never moved again. Oops.

I tried this again today. Same system, and Trident Executive again. For this time, all went just fine and I earned my bounty.

So I suppose that something has changed in the game mechanics since 1.76.1 and 1.82, because the derelicts sometimes got stuck on the final approach to the Dredger ship.

Sorry for bad English.

I compared the Docking A.I. script (dockingAI.plist) for 1.76.1 and 1.82. Here's the difference:

So I changed the dredgersDockingAI.plist to
Code:
...
    APPROACH = {
        ENTER = (recallDockingInstructions, "setSpeedFactorTo: 1.0", checkCourseToDestination);
        "COURSE_OK" = ("setSpeedFactorTo: 1.0", performFlyToRangeFromDestination);
        "DESIRED_RANGE_ACHIEVED" = (requestDockingCoordinates, "setStateTo: AWAIT_COORDS");
        "DOCKING_ABORTED" = ("setStateTo: ABORT");
        "COLLISION" = ("setStateTo: ABORT");
        "RESTART_DOCKING" = ("setStateTo: GLOBAL");
...
    "GO_TO_COORDS" = {
        ENTER = (performFaceDestination);
        FRUSTRATED = ("setSpeedTo: 0.0", performFaceDestination);
        "FACING_DESTINATION" = ("setSpeedFactorTo: 1.0", recallDockingInstructions, performFlyToRangeFromDestination);
        "DESIRED_RANGE_ACHIEVED" = (requestDockingCoordinates, "setStateTo: AWAIT_COORDS");
        "DOCKING_ABORTED" = ("setStateTo: ABORT");
        "COLLISION" = ("setStateTo: ABORT");
        "RESTART_DOCKING" = ("setStateTo: GLOBAL");
    };
...
So far so good - no more derelicts stuck on the way to the dredger. Please correct me if I'm wrong.

Sometimes it helps to repeatedly request docking clearance using key_docking_clearance_request. While they don't require it, that seems to stop them from moving away from the incoming derelict. May also help when docking yourself.
Docking yourself and buying something that costs some ingame time (e.g. fuel) also often "fixes" the problem, you get the message about successful salvage as soon as you undock, most of the time.

Thank you, I applied your fix into v2.4.8 together with some waipoint handling. Please update and test it.

Whenever I try to salvage something to a super dredger, the auto pilot wreck goes into a "just move farther and farther away from the dredger in a straight line" mode when coming near to it. There is a way around this: Most of the time, docking with the dredger (normal or super) and buying something that costs time (e.g. fuel - always a good idea to fill it up when there's a chance to do so, even if it's expensive) causes the usual salvage message to appear after relaunch, money included. Works with any station IIRC, the dredger is just the nearest one. This is perhaps also a bug but as it's the workaround for the above bug shouldn't be fixed.

In v2.4.9 phkb converted subentity definitions to the new format to remove warnings from the log file.

Hi! I just docked with a Dredger in Anlama system, very near the aegis. I have only resumed Oolite again this summer after some years, so checked on the Oolite wiki first, to be sure a Dredger really could be docked with and would not just swallow my ship into its maw as scrap!
(I think now I may have docked with one or more, long before.)

Anyway, the Dredger was advancing slowly and kept moving when I hit shift-L for docking protocol; it said 'come on in' or some such, but didn't pause and even seemed to begin turning as if to avoid me. I had some near misses (avoiding collisions), then found what worked was to get a fair bit ahead of it, very roughly in line, then to head slowly away - maintaining distance while looking in my rear view and repeatedly adjusting my direction of flight slightly until I had achieved alignment with the striped entrance channel. I stopped completely, and slewed round to again centre it. I hit shift-L again to be sure of a welcome! I could have just waited for it to reach me, but increased speed if impatient then slowed right down on entering; the Dredger's own forward motion is right for docking. Another plus is that, unlike stations, there is no spin to match - just line up.
