I was shooting around a modified kytryn launcher, I shooted the domina station in Eridani and I've got this error.
If necessary, here is the code of the weapon:

I've had the same crash:

The weapon I was using does not have any fragments though. I just assumed there was some bug in my weapon that was made for 99c. It's a insta-kill weapon on my debug ship.

Thank you! That crash is fixed in RC3.

The problem is a bug in Order=12 (AttackNearestEnemy).

Oh! This reminds me. Somewhere in .99 the "bug" that made my Stephinian Missiles fun to use got fixed. The "bug" was that fragments only came out of the left side of the missile, so it did almost zero damage unless you were to the left of your target. Perhaps you could implement a FragmentationAngle thing to bring this functionality back? Without it, the Stephinian Missile is just boringly overpowered.

mmmhh, George, is this same bug ?

I've got it in RC3, I was shooting a centurion just next to the Domina station in Eridani to test a weapon.

mmmhh, it happened again, I was simply docking at a station and browsing items, when he crash happened

I really think this must be related to some mod (since no one else is reporting it).

The one constant is that all the crashes are in ships with a valid target, which means that they are trying to attack something. Is it possible that a mod overrides some weapon?

Bobby · Tue Dec 29, 2009 10:10 pm

does anything inherit from another ship class?

I was getting some hard crashes like that when I pressed "c" and there were ships in the area that inherit from a base class without a <Communications> tag, I don't have the message though, and adding a message with a nil <onShow> works fine.

I didn't know about that crash--thanks for mentioning it. I've fixed it in RC4.

yes, I'm overriding all the weapons of the game, that's why I think I'm doing something evil.

So here I pasted what I'm doing on the ship that 9 seconds later crashed the game.
So first I remove the EMP cannon (the blue one is the standard vanilla one), then the script try to find a weapon that has this criteria :
w~m -Launcher; -Ammo; +Ion; +Illegal;
w~m -Launcher; -Ammo; that's the base criteria
Ion because we replace weapons with the same damagetype
Illegal because the sovereign is svPirates, so it has 40% of probability to search for only illegal weapons.

Result: no weapon is found and the EMP cannon is mounted back on the ship.

Then the shield is removed (class II), and replaced with a class II.

10 barbary-class ships like this were spawned, all attacking the gplayership.

here is another

George, I did some more testing, I think it's on my side, however I still have no clue where is the bug.

(it seems related, on first look, to the part of code that reinstall the old weapon back on the ship)

Wed Dec 30, 2009 12:18 am

If it's relatively easy to reproduce, just send me the files and I can reproduce it under the debugger.

Wed Dec 30, 2009 9:07 pm

resolved, It was a bug on my side, I was trying to reinstall a weapon on a AI ship using the same itmStruct that I used to remove the weapon from the ship.
