Mobile launch black lights/materials

Hi, first of all, thank you for taking the time to help.

So, my issue is with the lighting i guess, i´m trying to preview a project in android, this project was compiled and launched succesfully before and had no issues.

for i reason i havent found yet my game now looks like this.

as you can see i can see only unlit materials/textures so i guess it´s not a textures issue and should be a lighting isue, in scene i have 68 spotlights inside/outside the house to help get a smoother lighting, all of them are static.
i have a directional light, a skylight and a atmospheric fog all of them static.

everything was working fine but the lightmaps where too compressed so i changed some settings:

MobileHDR is off
Lightmaps are compressed (Uncompressed my phone gets ou of memory and gives an error)
pvrtc compression is at 4 (Wont do a difference switching from 0 to 4, still black)
And the skylight doesnt cast shadows.

i dont know what else to do, any advice would be really helpfull, thank you for your time!

Edit:

Why the log shows the Buildmap and the Map in 0% and 1%?

Ok, is the stupid Map, there´s something wrong with that file.
made a new map, copied everything into it, rebuilt the lights and voila!

if anyone has a insight of what could have caused it i´d love to know, it´s fixed but in a very un professional way haha.

No, wait, is not resolved, the mas was indeed one issue, now i got another.

The lightmaps are not being transfered to the android platform, in windows runs without issues but android doesnt have the lightmass info and asks me to rebuild the lighting data…

i´m confused

Really it could be anything that could have gone wrong. Sometimes data can get corrupted and it is always a good idea to keep backups and copies for situations like this. (not much you can do about a map though other than see if the backup works in your saved folder).

Be sure to keep a mental note of what you are doing. In case you trigger this again it could be possible you are doing something that is causing the map to not load properly. Remembering what happened prior to the issue could lead to a list of steps that allows us to reproduce the issue and therefor have a way to test and fix it(if it is a bug with the engine).

I´ve tryed rebuilding the lightmass, changing quality settings, merging everything into another project, making a new map and placing everything together and nothing really works, the only way i was able to import it into android was with an empty house (Builddata was around 7mb)

with all the objects Builddata goes up to 700mb aproximately and i no longer can import it into android, how can i controll how big is the build data?

Right now i´ve clamped all lightmaps resolution from 32 to 512, and the lightmass is still too big.
