This happened few days ago, before everything was fine and now I have this weird light bug (looks pixelated and it's shimmering) mostly in longhouse but it can happen in other buildings. I really don't know why this happened and would be really happy if I could find a fix. 
Hey all,
I apologise for the delayed response to this thread. We have forwarded the information and images about what is happening and the workaround to reduce the effect of it to the dev team so they can look into this. If they need any further information, we'll get back to you on this here.
Hello there!
I'd like to reach out to you all from an update from the investigation into this light issue. The development team are interested in collecting the system files of players who have encountered this visual issue in their games. To help us to collect these, I've now opened support tickets for @WoodyRowes, @geminixnet, @Makfrois, @Simplethumb, @RodroG-85 & @Knugenboze. You can find these by logging into the Ubisoft Help website and selecting "See All Cases" on your main homepage. You should have also received an email from me which provides you with instructions on how to collect these system files and how to upload them to your ticket.
Once you have updated your support tickets with your system files, please can you let us know within this thread? We can then ensure that they have been forwarded to the dedicated teams for a closer look.
Thanks! 
Hello @RodroG-85 and thank you for attaching those system files. I can confirm I have forwarded it to the development team for a further investigation.
Please let us know if you have any other questions.
Hey @RodroG-85, appreciate your detailed input regarding the issue and we will try to keep you all in the loop, therefore as soon as more information becomes available, details will be posted here, in our official forums, so keep an eye!
In the meantime, if you do run into any other difficulties, let us know!
Hey there @rodrog-85, thank you for getting back in touch. I have gone ahead and looked into it from my end and I am afraid we do not have any updates to share at the moment. I want to assure you that the investigations are ongoing and the development team are still hard at work. Once we have more information available, we will post it below. If you have any questions or run into any other issues, please do not hesitate to let me know.
