Game crash after fire trap causes multiple potions to explode #13

What account do you play under on Hardfought? K2 hasn't found any crash logs or anything to restore. Is it possible you disconnected from the server at that time? |

Account name is It didn't seem like a disconnection - I'm playing on Windows using PuTTY, and when I disconnect usually there's a error message and I have to reconnect, and the game is recovered. With this, there was no reconnection, no need to log in again, I was just at the Hardfought play selection menu. Since it was potions exploding, it seemed similar to #10, not sure if there's anything to that. |

K2 discovered an emergency save which was playable, but I loaded it and didn't find anything broken when repeatedly stepping on the magic trap. The paniclog contained an 'extract_nobj: object lost' panic, but I don't know if this was related to your game. If it was, it could be related to the trap ammo code, which contains some extract_nobj calls, but I don't see how that would happen as magic traps don't have ammo, and the trap wasn't being destroyed. For now I don't have enough information to figure it out. Shouldn't be related to #10 as that specifically dealt with wetting items and the acid-water interaction; there's no general exploding potion code. If you tell K2 you want your game recovered while you don't have some other game in progress, he'll recover it for you. |

Thanks, I appreciate the investigation! I've got another game going now, so I'll just chalk that up to a strange YASD :) |
Partial merge #13 of vanilla. No noteworthy conflicts.
If you were on a level teleporter, the spoteffects() call after
the hero gets expelled could end up going to a new level and
freeing all the monst chains from the level you were originally
engulfed on.

The latter parts of xkilled() after the spoteffects() call would
then attempt to dereference the free'd monst pointer.
Save a copy of the monst struct prior to spoteffects() if you were
expelled, then point at the reference copy afterwards.
Resolves #938
Hi there, just had a game crash (playing on Hardfought, xNetHack 5.1) after I stepped on a fire trap. I got the "flames erupt from the floor" message, my shield smouldered, a potion exploded and I healed a little bit - and I was prompted to name that potion, then another potion exploded "strange feeling for a moment, then it passes", I named the second potion, and basically as soon as I hit enter with that name I was back at the Hardfought home screen - no more messages, no dying, etc. Starting up xNetHack again I got the new game screen.
