[BUG] The toxic conduits (plagued rats) [Solved]

I killed doedre last night, took the wp after her and quit.
Today I took a random prophecy, plagued rats, and it procced when I entered The toxic conduits wp.

The area is a post-boss-room zone, so you can not walk back in.
It's only a short tunnel to the left, exit into the promenade, and the right side tunnel is also a exit into a new area, the Quay, both which deactivate the prophecy.
When you type /remaining it says over 50 monsters but you can't find any monsters or rats.

You're probably as confused as I was if this happens to you.
Here's the solution:

Enter the toxic conduits from the town, the sewer pipe on the west side.
In there you won't see the prophecy yet.
Make your way to the next instance door within 5-10 minutes before the "doedre's cesspool" area or
"toxic conduit WP" instance with the rats deletes itself.
When you enter that door, you are in the pre-area of the toxic conduit WP, before the doedre boss fight room. You can find the rats here now.

Pretty fucking confusing spot to have prophecy spawn at a WP which doesn't allow you to go back,
and the pre-PRE-area of that zone doesn't show the prophecy either.
Could have had some better logical consistancy imo.

That was helpful. Thank you!
