NPCs stop reading if player uses stairs

[pwalsh0]

Describe the bug

As subject. Imagine a "training montage" with lots of npcs in library, all carefully ordered to study from a book or tablet.

This training montage gets interrupted if the player uses a stairs briefly then returns - all the npcs will stop reading - and then require tedious refreshing of orders.

Doesn't seem to interrupt crafting or other activities, just reading.

Steps to reproduce

Load save. Check if npcs are reading, if not give them orders. Not sure if loading save interrupts this as well. Note npcs nearby are reading books. Note they will stay there and not follow. Go up stairs then back down. Now note npcs have stopped reading and are following player again.

Expected behavior

NPCs should not stop reading just because the player uses a stairs.

That should have been fixed when 3D view was made mandatory. If your game version is older than that disabling 3D view should get rid of the symptoms (it was caused by light checking code that failed to actually get hold of the light level on other levels).

If the version is a new one there is still a problem, but walking downstairs and ordering companions to read, return back up, and then down again does not interrupt reading for me using code downloaded and compiled earlier today.

The version from above is cdda-experimental-2024-02-10-0823 - is that recent enough?

edit: @PatrikLundell confirmed again with latest experimental 2024-02-13-1429

In this case the "reading room" is underground with a lamp - maybe that makes a difference compared to npcs reading in naturally lit area? In OP I said that crafting wasn't affected. There is a workbench at ground level with another npc crafting away - and he does not get interrupted by player stairs travel. So suspect lighting problem?

Tested some more - and confirmed this only happens when reading with artificial light source.

If you bring the guys outdoors and tell them to read under natural light they don't get interrupted.

I have had my NPC stop other tasks in a similar fashion when I change z-levels, not just reading. And yes, underground I was using artificial lights.
