NPC Spawn Issue: I don't think phase spider traps should exist

[Ciroco]

So I was trying to find if there's any proof that phase spiders spawned from traps are supposed to be staying up indefinitely as they currently are, but I actually couldn't find any evidence from Live that they exist at all, and certainly not any classic evidence.

The guides below go so far as to list the various types of things that can happen when a trap is activated, and none of them mention a phase spider spawning.

The only websites that mention "an out of phase spider", which name of the invisible trap NPC, are other emulator server sites.
The only website that mentions the emote that happens when you activate one of these traps ("an out of phase spider phases in!") is this post from our forum.
