[RCI] Infinite lue error report, crashes game

[martinuzz]

I opened a vault door in Dreadfell, and got sucked into it by some teleporting horror I think. This caused the first error report screen to pop up. Pressing close, or close all, just popped up the next error report screen. There is a miniature version of the error report screen on top of the error report screen as well. See the screenshot. The first time, game turns kept progressing in the background, despite the error report screen, for every key I pressed / mous I clicked. Eventually I got out of the first loop, and into the Eidolon plane. But after returning to the vault, and firing a spell at the luminous horrors in there, I again got sucked into the infinite error report loop. This time, turns do not keep progressing, so I can't get out via the Eidolon plane. I will have to kill the Tome process with the task manager, as I can't use escape to save and exit either. Since I can't send the report ingame correctly, here's a screenshot. It's only partial, this happens after alt-tabbing out of tome. I cannot recenter the full screen. Luckily the essence is on the screenshot.

If you like, I have a save with this problem. The game saved on the Eidolon. If I load up, and choose to go back to the vault, the bug is there ready for observing.
If you like to have it, tell me which files to send where pls.

Thanks for the report. It's caused by creatures with the backlash talent taking environmental damage.

DG: here is a (quick and dirty) diff to fix it:

Code: Select all

fixed thanks

Is there any way I can implement that fix for my current savegame? I hadn't gotten past level 20 in ages, this is one promising char, but can't use the save as it is.

This or something like this also exists in RC3:

Code: Select all

I can't tell if the game still proceeds underneath the infinite error report screen, which also doesn't work in its own right (you can't type in the description field).

It's not in Actor.lua, so maybe it's something else, but the symptoms are the same.

Screenshot:


The game log is just the error report over and over again (makes sense, since it's trying to send it over and over again). If you let it loop long enough it just eats all the cpu.

Here's a new one:

fwiw I compiled the game from source and still got the above error.

[GreyMage]

In RC3 I have, what seems to be, a similar Lua error. This in Bellow 3 with a dwarf bulwark against the Mouth after it pulled the character for the third or fourth time. The error dialog is on infinite loop and will eventual eat all available memory, or so it seems. I had to kill the process with the Task Manager (windows xp box)

Lua Error: /mod/class/NPC.lua:171: attempt to index field 'target_last_seen' (a number value)

Hope this helps.

EDIT: Although, this may be fixed in SVN for RC4(?)
