ToME: the Tales of Maj'Eyal

It seems that sometimes a monster will become untargetable, invulnerable, invisible and unable to move... but able to cast talents. I posted a more detailed bug report here: http://forums.te4.org/viewtopic.php?f=42&t=40945

Unfortunately, in my case this happened with one of the boss orcs (Gorbat Pride).

I tried leaving, deleting the map so it regenerates, and then returning, but it seems that the boss did not respawn with the rest of the dungeon.

Is there a workaround to re-materialize the monster in question?

Since I wasn't getting a response on this, I decided to look into whether I could use debug mode or edit my savegame or something as a solution.

Apparently debug mode would invalidate my save, so I didn't do that. And I didn't want to just set the Gorbat part of the quest to complete, or even the main quest, because I wasn't sure whether I would then miss triggering a chain of event triggers.

So I started messing around with the save file for the one remaining NPC in the Gorbat Pride map (mod.class.NPC-...), who turned out was of course the boss in question. I tried setting life regen to -100 and other things to cause him to die. I would leave Gorbat, make changes, then reenter and see if it worked. But nothing seemed to have an effect.

Finally, I tried a simple thing: I shifted his "x" value over -2 units. When I reentered Gorbat, he was visible! I got to have my big boss fight after all.

Hope this helps someone else! (But mostly, I hope the root cause of the bug gets fixed.)

What was his X value before you changed it? Was he at the right edge of the map? Did changing the X value actually move him or just make him visible?

When hearing these stories, I've been suspecting that Bosses have been somehow getting shifted beyond the map borders. I'm wondering if that's the case here.

He was on the right-ish side of the map. The x value was 49. I think I shifted it to 47... though I'm less certain now, as I also remember the number "44" as my target. I can't check anymore because he's dead and gone.

No worries. Glad you were able to fix it.
