Lights don't stay deleted

One of the first acts of splurge for me was playing with the lighting previews. Mixing colors, values, spots, omni, etc.
Everything is cool until I start deleting lights. They disappear from the grid/3D space, but they are still "active." If I save, close, and reopen, they come back like I never deleted them.
Not a seriously big issue right now, I can always make my geo and do lighting last, but I thought I'd share my findings.
Sorry if this is already listed somewhere. :P

It sounds like the delete flag for entities is not being honored somewhere.
Brian: When you say the deleted light entities are still 'active' do you mean they still affect a lightmap preview? Is your "save, close and reopen" operation with CSX files or directly with MAP files?
Jaimi: Thanks for the info.

Yes they still remain active even if not visible :)

Right, it's just as Petteri says for me as well. I've only messed with CSX files so far.

I'm trying to reproduce this at my end and so far haven't been able to. Here is my basic test case:
1. Create a 16x16x16 cube.
2. Add a light_point entity in front of one of the cube's faces. I changed its falloff_outer to 100.
3. Switch the Perspective viewport to use the Mapped lighting option. Do Scene->Relight All to make sure the light entity is working, and it appears fine.
4. SHIFT-drag out two copies of the light entity and place them around the same cube face. Do a relight and they look fine.
5. Delete the first light entity and it is removed from the viewport and scene entity list. Do a relight and the lightmap looks correct with the remaining two lights.
6. Save the scene as a CSX file. Close all scenes. Reload scene and there are only two light entities present. Do a relight and the lightmap looks correct.
7. Delete the two remaining light entities and they are removed from the viewport. Do a relight and end up with a completely black lightmap.
8. Save scene again. Close the current one and reload. All light entities are gone. Do a relight and have a black lightmap.
Is there something that I've missed that would make my steps different from your own? Are you using a different light entity?
Thanks.

After long session of relighting, if I happen to have done some undo, sometimes light will keep light points I deleted previously, with the points in themselves not being here anymore Oo.
After that, if I close and reopen, the previously deleted points will come back Oo.
The trick is that every time it happen I did undo at some point, and I did a lot of relight.

But the more lights I add and delete, the more likely I am to get the error. It may be an undo issue for me as well, I tend to use redo/undo a lot as I tinker with various settings.

It's kind of been hit and miss trying to replicate the problem again.But the more lights I add and delete, the more likely I am to get the error. It may be an undo issue for me as well, I tend to use redo/undo a lot as I tinker with various settings.
