Workaround for npc teleport

[thokkat]

In vanilla Npc_ExchangeRoutine teleports npc's to new routine waypoint if they're offloaded from world. Examples are Greg-Dexter event and ring of water meeting. The idea is to imitate this by resetting far npc's if their routine is exchanged.

Hm, thanks for raising this issue, bug unfortunately this solution is too big of a hack, and we should not merge this PR as-is.

You checking for ProcessPolicy::AiNormal - that's find, but destination waypoint might be observable by player. If you check for wayPoint and for npc, it probably wont be a 'fix'.

I was considering to teleport npc forward along his way-path, while whole segment of way-path is not visible. Yet it's hard to reason about path visibility, specially from CPU side

Yeah I was aware of the concerns you raised in #420. But I mean if this ever happens it's surely out of vanilla render distance and I'd say an ok tradeoff for getting several events working in return.

This sounds even more hacky :D. But as you said above adding a ray between player and waypoint makes workaround only bigger so feel free to close.
But I wonder what a solution could be. Only thing I could imagine is script patch where every call is checked and AI_Teleport is added if not visible by player.

starting a new issue, to discuss on how implementation may look like: #585
