At '5199,85,5,0' there is an NPC which cannot pass between two display cases. This is not passable by GM as well by some reason.

I don't think this issue makes any harm in my case except printing error messages, but posting for sphere developers consideration.

Do you have some npc ai enable on the ini?

If you have time and are able reproduce easily, will be interesting to know witch npc AI generate this. You could inactive some of them to test. Probably 01 or 0800

Jhobean avatar Oct 04 '21 15:10 Jhobean

I will try, by some reason it happens on a live shard (8-14 times a day, 2 NPCs are logged, another one cannot access their spawn point as well) but does not happen on home sphere with the same save files.

a1exp avatar Oct 04 '21 16:10 a1exp

@Jhobean

  1. removed 0400 - no chage
  2. removed 08 - no change
  3. removed 01 - error messages are not reproduced during 7h already, so NPC_AI_PATH might be the flag which was causing this issue.

a1exp avatar Oct 05 '21 15:10 a1exp

Is this still happening?

cbnolok avatar Jul 31 '24 08:07 cbnolok

i recently had this within the last couple months. and i found that it was an NPC trying to move into a boat region but could not. i wasnt able to move the NPC at all by '.xmove' or 'teleto' or 'p', the only thing i could do was delete it, and immediately the console errors stopped. perhaps that information is of some help tracking it down
