[b35] crash with adventurer party (AI?)

[jotwebe]

Cast "Redux" and then "Turn Back The Clock" on a adventurer, got an infinite number of error popups. Actually, after killing t-engine and reloading, I get the exact same thing after using a staff of ruination instead.

This is the console output (repeated):

Code: Select all

Thanks for posting the error. The problem is not what you are doing, but what the adventurer is trying to do. If possible can you find what is going on right before the Lua errors? I am specifically hoping for a tactical AI report, which would look something like this (taken from http://forums.te4.org/viewtopic.php?f=42&t=25050):

*** AND NOW THE LUA ERRORS***

All right, ran it with putting stdout into a file now so Icould get the good bit:

basically

Code: Select all

After that it runs in a loop...

Oh, I forgot that DG suppressed the tactical AI stdout which is why you are not seeing the extended tactical report. Alright, at least we know that the problem is a specific talent that "Osassar the shalore" has. Would you mind inspecting that actor and giving me a list of the talents he has? Thanks.

[jotwebe]

Here we go:

Blurred Mortality 3
Create Minions 3
Displacement Shield 2
Invoke Darkness 5
Magic of the Eternals 3
Necrotic Aura 2
Shatter 2
Teleport 2
Trap Detection 2

[yufra]

That helped a lot, I found the bug. The error was caused by the Shatter talent, although the actual bug was in not checking for nil values in the tactical AI code. I have attached the patch to fix it and will let DG know. Thanks again for all the debugging help!

[jotwebe]

No prob. Thanks for debugging

Is there a way to incorporate this patch manualy into b35 (ie myself)? This bug happened a lot to me and my latest char is kinda stuck because of this.

He is in a Farportal dungeon and the final boss triggers this bug everytime.

Hmmm, well just know that it would invalidate your "clean game" status so you wouldn't upload to the character vault anymore, and the unlocks wouldn't be available in the "clean" b36+. You can fix this by finding the tome-blablabla.team file and unpacking it (it is actually a GNU-zipped tar archive). Then apply the patch, re-tar/zip the team file and get going. Alternatively, enable cheat-mode and teleport yourself out of the Farportal dungeon. Those are the most obvious fixes.

Thanks!

The patch worked. Haven't played extensively yet, only tried to kill the boss that was causing the problem. But no lua error =)
