Strange ship behaviour

Hi,

seems today ain't my day...fix one problem and several others arise. Good that I finally learned about shift-h.

First I had an encounter with a thargoid cruiser...but it was running from me. It's AI was attempting to fight me, though?!?

Any suggestions?

Then there's a derelict boa class cruiser without autopilot, but running from me:

That is a bug in the Dredger.oxp script. I add a trader from the pool of installed traders and give it a new AI to become derelict and also add "derelict" to its name.

This special trader has a startup script that changes its own trader script into one that also tries to dock at other stations than the main one. (when has_npc_traffic is true for that station)

Anyhow, this startup script overrules my derelict changes. I'll already have an idea how I must handle this exception.

I first "lost" it during a combat, later found it again when I went to the main station...there was a GRS station in the system, but it tried to dock at the main one. During flight it was so fast that it did outrun the salvage missile...when it tried to dock, I fired another one, which was able to "catch" it, but failed because it wasn't an abandoned ship

The BCC even stopped the docking attempt and tried evasives, however it was so close to the station that it was unable to run at that point.

Seems there's still the question concerning the thargoid ship. I had some other encounters where pirate ships did not return fire. One time it tried to move to my twelve (where it was), the other time it tried to reestablish formation (formation form up). As if the AI in such cases does not care about being shot at...but then in those two cases my lasers might have been too quick for them

This is true. We seem to have plenty of ships trying to execute attack twelves lately, with some notable "I don't care if you shoot me" behaviour, also in the trunk code. Well, one more for the bag of bugs, I guess
