NPC Tagging showing incorrect tiles for moving NPCS

[west mica]

Date last experienced: February 3rd 2026

Device & operating system: Galaxy A03s / Android 13, but the bug isn't device specific, it happens on the PC vanilla client too.

Which client version is your app showing: 236.1

What content is primarily affected: NPC Tagging on moving NPCs

Do you know of a current work around?: No.

Before 236.1, the highlight around tagged moving NPCs would always surround where the NPC was visually, smoothly moving between tiles as the NPC moved.

Now, when an NPC moves North or East, the highlighted tile lags behind them, and when they move South or West, the highlighted tile jumps ahead of them (almost like it's following their true tile, but northwest / southeast movement shows that isn't the case.)

Video is from the PC client for ease of recording / uploading, I tested identically and I'm sure others can vouch for me that it is in fact identical across devices.

Hey Flant, if you are having issues you can report it in game as well as here. https://support.runescape.com/hc/en-gb/articles/360001355429-Report-a-bug. Have you uninstalled the game and tried reinstalling it? I wish I could be more helpful.

im well aware of the general bug report system, i'm only posting this here for the sake of mod blossom being able to easily forward this to the people working on the client. you don't need to help me

Thought i would try my highlights, outline of frost dragon is highlighted but no square around it. Jesus christ mobile is a complete mess

And no doubt tagging a frost dragon to test highlighted 10+ other random npcs and objects that I now can’t turn off and probably will have to reset all my npc highlights

My npc highlights are also kinda bugged but i'm just living with it. Used to be just tool leprechauns and all impling types but now since i marked the zarosian spiritual mages, lots of weird stuff got marked, some of which doesnt even have interact options or examine options and isnt even an npc. This includes:
the axes at vardorvis (cool, maybe i can tile skip...)
The attacks from zebak, but the rocky parts only. Kinda annoying. And there's a 5x5 highlighted under it too.
The butterflies in lletya.
The lightning attacks from rune dragons.
The strange creatures which were supposed to disappear after mm2, are just invisible and you can still see their true tile since the highlighted tile is moving around with nothing else.
As well as all kinds of other stuff.
