for some reason the bots are crashing when master teleports

[trickerer]

reason can be only if bots are going out of map bounds

I have the same issue when I die with NPC bots

Seems like it might be related to TrinityCore unresolved issue....

https://github.com/TrinityCore/TrinityCore/issues/3953

Liho's fix doesn't allow you to summon npcbots anymore though. :(

Kaelima's does nothing...

[David Magalhães]

for me it seems fixed

[Nobody]

Mine is only with NPC bots. Playerbots seem to be working fine now for me. Sorry for the confusion. I should have opened a separate issue.

Why is that? Crash every time player dies? Also, do you always get warlock npcbot?

[Nobody]

Yes, crash on death of player...I Think I do always get Warlock npcbot, I've been using them to test 10 man content, so I have at least 1 of each class in raid.

[trickerer]

for now this code part looks like:

void ObjectAccessor::RemoveCorpse(Corpse* corpse)
{
    ASSERT(corpse && corpse->GetType() != CORPSE_BONES);

    //TODO: more works need to be done for corpse and other world object
    if (Map* map = corpse->FindMap())
    {
        corpse->DestroyForNearbyPlayers();
        if (corpse->IsInGrid())
            map->RemoveFromMap(corpse, false);
        else
        {
            corpse->RemoveFromWorld();
            corpse->ResetMap();
        }
    }
    else

        corpse->RemoveFromWorld();

[trickerer]

I guess your crash is related to walock pet. Please create separate issue

[David Magalhães]

solved
