I'm having a bit of trouble with a hotspot. I have hotspots working correctly in other scenes, but after creating a new scene to try to replicate an issue I've run into with a different asset (Dialogue System), I seem to be unable to use the hotspot in the new scene. No icon change appears on mouseover and it's not clickable.

The new scene consists of:
The same scene manager
A cube game object functioning as the ground plane
A game camera with identical settings to previous scenes, assigned as the default camera
A cube game object with the hotspot attached
A hotspot with the identical settings to previous scenes
A "hotspot:talk to" interaction with identical settings to previous scenes
The attached action list which is also identical
Dialogue System's dialogue manager prefab (same as previous)

I've combed over every single thing I could think of to check if there were any differences between how I'd set up the scene or hotspot compared with previous scenes where the same hotspot worked, but can't seem to find anything.

I've tested out a trigger with the same action list and that does work, so it seems to be confined to the hotspot/hotspot interaction somehow. The same issue seems to occur with any hotspot I add to the scene.

Quite perplexed by this - if anyone has any suggestions they'd be warmly welcomed.
