Our hot cold solver can be inaccurate sometimes due to some of our locations not being correctly centered in code. This is a mega issue to track which ones have been centered or not.
The master dig locations are a 9x9 square and you can find this easily by spamming the locator orb.
Example PRs are #9450 and #9486, if you help tackle this issue please provide image proof. (Please use the location dev tool or capture the blinking hint arrow in your screenshot)

Spots which have already been centered in master:
Eastern part of Piscatoris Hunter area, south-west of the Falconry.

South of the Fight Arena, north-west of the Nightmare Zone.
Interesting that it goes inside the building

McGrubor's Wood is already centered

Question for hacktober/first time contributors (myself included): is there an easy way to test this without having the clue in question? Ex. is there a flag somewhere in the clues plugin that can be turned on so that these hot-cold boxes are always rendered regardless of whether you have a clue scroll or not?
If so, that's a much easier way to check and fix all of these.
you would need the real clue to find the dig box and from that you can get the center point
There is not. We need to be able to get feedback from the server (via checking the Locator Orb), and that only works with the real clue.
Man, you guys are fast - thanks for the clarification! Kind of a bummer, but I guess it's an excuse to do a bunch of clues, right?
Any tips on getting these specific clues? Is it a specific clue difficulty that has them?
all of them are master clues which you can get from completing other clue tiers or turning in each of the other tiers to Watson
Here's a screenshot which may help for the "North-west of the Sinclair Mansion, near the log balance shortcut." clue. Apologies for the scuffed ground markers, but each of the items on the ground indicate a tile which was within the dig area.

For posterity's sake, the five beginner hot/cold dig locations should probably be added to the list in the OP, too.
@Nightfirecat, do you remember if you centered those spots when you added support for them?
The Beginner clues are correctly centered.
Hey, my pr for adding clue enemy info was merged earlier(https://github.com/runelite/runelite/pull/11309).
While doing this we found the hot cold step "East of the Wilderness canoe exit, level 35 Wilderness." was able to spawn either brassican or wizards according to the wiki.
When this step is centered, can we make a note to check this? The question is can this clue step spawn both or not.
Based on what Mod Ash said, it is possible to spawn either one. https://twitter.com/JagexAsh/status/1260508986383663110
West of Pollnivneach.

South of The Golden Field tavern in the northern area of Hosidius.
Text should be changed to match the wiki, as The Golden Field tavern no longer exists in that area since the Hosidius rework.

EDIT:
Got the step again and triple checked the area, as long as the dig spot is centered, everything will be fine.
Hm, are you sure this is centered then? It's possible the center is actually over the river in that case
It is centered, I checked top left corner, and the right edge.
By current dig spot I meant the tile with the spade. These are the 3 tiles that messes with the clue scroll plugin (they are out of the shot).

Oh, well that would be because our plugin currently thinks the dig spot is 4 tiles north of you. If you had made the needed change and built a new version, it would work as expected.
