Some Light Probes dark

As the title says, I'm having trouble with some light probes being very dark.

I've double-checked the position for the probes and they're not 'inside' the building or anything like that.

What really baffles me is that it'll get the probe right on one building and not another, and in the example on the right you can see a symmetrical roof area, and the probe on the left side is borked.

Likewise, the probes on either side of the fence aren't matching. Some are way darker than others for no good reason.

Any ideas/tips?

Using Unity 2018.3, HDRP.
I have about 8 gameobject Light Probe Groups, all marked static too, one for surrounding each building, and a few more for environment/background. Maybe a couple hundred probes all up.

 

I'll try the scales tomorrow, as well as the individual groups.

Realtime Global Illumination: yes
Baked Global Illumination: Yes
Lighting Mode: Shadowmask

Lightmapper: Prog. CPU
Prioritize View: yes
Dir Samples: 64
Indirect Samples: 512
Bounces: 4
Filtering: Auto

Indirect Res: 4
Lightmap Res: 12
Lightmap Padding: 2
Lightmap Size: 1024
Compress: yes
Ambient Occlusion: no
Directional Mode: Directional
Indirect Intensity: 1
Albedo Boost: 1
Lightmap Params: Default-LowRes

Here's a pic of the spider web. You can see the 'houses' that I'm talking about, the fence, and the giant temple. Also it turns out it's 11 Light Probe Groups total.

 

about to go through and retry the individual probe groups, but when I opened the scene all probes were brown.

Then tried setting the lightmap scale to 0 for all structures (not the terrain, left that alone). Getting some weird results, if the terrain albedo (presumably the basemap colour) more should be green, not just some tiny area?

About to try turning off probe groups now :S

OK, more experimenting on this.

Updated to Unity 2018.3.7f1

With just 1 light probe group, all seems fine.

With 2 light probe groups (named A and B), some probes are dark.

With groups A and C (different group) some probes are dark, but different probes compared to A+B.

This is repeatable; if I go back to A+B the original dark probes are dark again, and I can do A+C and get them to fail the same way as A+C originally did.

Tried combinations of A through J probe groups, different numbers on at a time, etc. often ended up with a could of oddly dark ones in strange areas.

 

Changed to Enlighten, that did the trick. All probes from all groups now lit correctly.

 

Hello, I`m using Unity 2019.3.2f. When I backed lights I got this. I`m using an emission material for it. With spot lights light probes baked normal

 

I'm using 2019.2.10f1 and have same problem with Progressive GPU or CPU ,its work fine only in Enlighten mode ,and i'm using an emission material too , playing around Lighting Mode or IG not make any changes
