I’d be willing to bet that this happened on the A map. This… is something that has come to my attention rather recently, and I’ll probably look into that soon.
For those of you who don’t know what a nodegraph is, it’s a file that is built every time a map is loaded for the first time. This basically gives NPC’s a map of the place, using all the info_nodes that were places in the editor. You can find this file in the maps/graphs folder.
I suppose that changing even a single property on an entity (changing the target of a changelevel trigger, for example) requires an entire rebuild of the nodegraph.
But seriously, why did this thread suddenly turn quiet?
