The hold has a demo from title screen. Something in said demo is most assuredly broken, because I get chased by a wisp not attached to a slayer.

How to reproduce this bug:

1. Lay out a wisp path.
2. Push the slayer to the middle of the wisp path. Make sure he's either on the wisp path or touching it, so he will not recalculate wisp path.
3. Use weapon movements to trigger his defensive maneuvers. Getting him moving in this way will cause a branch in wisp path.
4. Self-intersect the wisp to cut off the path. Specifically, you need to cut the path before the branch point.

If every step is done properly, there will be two segments of wisp left: the dead branch that is connected to the slayer, and the disconnected root that will persue the player.

Then, when the wisp is triggered, the slayer follows the dead branch to its end. Then the wisp is totally reset, everything becomes normal again.

So, in short, there are two bugs in here:

- The slayer performs a check if he's connected to the wisp, but not if he's connected to the root of the wisp
- The slayer also does not check if the wisp is totally connected

My slayer fu is bad. I'd like to request a demo or two that show the problem occurring.

My solution was to make it so that pushing slayers will extend the wisp back from them immediately. I don't know if it's still possible to create an identical situation as before but I hope not.

Just to be sure I understand correctly: under the new behavior, if a slayer is pushed, that slayer's wisp will disappear entirely? Or are you saying something else?

No, I mean the wisp tile will be added to the tile from which the slayer was pushed (as if Slayer moved under pressure from Beethro being close), to maintain the existing wisp.

Like this: (w=wisp, S=Slayer, .=floor)

....
ww..
..S.
....

When slayer is pushed E:

....
ww..
..wS
....

Okay, that makes sense. And if you push the slayer onto the wisp, that tile gets "used up" as if he had moved there on his own?

If that's true, then I think the only potential problem is if the slayer doesn't recalculate his path properly if pushed to be adjacent to the existing wisp. Haven't downloaded a beta version yet so I haven't checked what happens with either of those cases.

What happens when you push Slayer onto an existing wisp is that he continues chasing you as normal, and if the wisp catches you he'll step on the wisp piece that's next to him and closest to the player, so as usual. He won't suddenly decide to recalculate the whole wisp when he's pushed onto it.

Can confirm in 5.1.1.alpha.2020-10-18 that by watching the attached demo the buggy behaviour I see in the last stable version does not happen. Instead the wisp path start tile correctly extends and moves with the slayer.
