An alternative fix would be to unsubscribe from Steam and manually download off Nexus Mods, @Younesmegou12. It might work, it might not. If it does work than it is an issue with the Workshop.

@Strudeler of the Tart Society, I haven't used any mods on the granary, and it was on a brand new save without loading. The files don't show any line of code or error.
The Baserri has simply not worked (it was my first game with it so there isn't really a precedent), but the rest of the mod works well: I got the whale ressource, the Navarrese company can attack both in melee and distance, the culture bombs work...
All the mods I have installed when starting this game were working well, and I always take away the mods that don't work.
The monthly updates also didn't create any problems.

I tried Baskonia again, @Younesmegou12. The Baserri is working for me as intended just as it appears in the screenshots.

Let's start with these questions:
Do you have other mods on; any that change the Granary?
Have you loaded any saves (if loading can break UI then maybe it can break the Baserri)?
Do your log files describe any invalid or erroneous lines of code?
Has the Baserri worked previously?
Have there been other mods you have played that have broken recently?
Are there other aspects of Baskonia that are not working (culture bomb from Fishing Boats, Navarrese Company, bonus Whales, etc.)?
Have the monthly challenge updates been causing issues (sometimes any update from Firaxis can cause havoc)?
Have you recently verified the integrity of game files (sometimes Firaxis updates can alter the core of the game in unintended ways)?

Hi, I've been playing this civ and I noticed that the unique building didn't actually do what it was supposed to? You can build it without a granary, and it doesn't actually give bonus food to fishing boats and farms.

I've said as much privately but your Don Quixote mod is my absolute favourite. Anyone reading this should go download it because Strudeler's hero units are the coolest.

Also I've been harassing him to add more hero units but he won't do it.

Of all your mods I like Argentina the most, followed by Aragon, Naples, Portugal, California, Britons, Canton Castille and Baskonia. Thanks for continuing to create content for the community!

yeah, updating the old civs for TSL spawns would be fuckin lit. tsl players eating good lately.

It is now 2024 and, had I been insane enough, I could have released something else but, thankfully, Baskonia is the last mod of the year. What was everyone's most loved and most loathed mod I put out in 2023? I think updates to older mods also count.

Great mod as always! I can't wait to see what you have in storm in the future, your civs are always a lot of fun.

Thank you for your kind words, @Pitu_Chulipiruli. You may recall that I release mods sporadically and I cannot guarantee when I will release the next Iberian civilization. Your proposal for Aisha al-Hurra is being considered.

Thank you very much for this new civilization of the Iberian peninsula, you show a lot of interest to keep this great game alive, I am going to try it right now. I would like to suggest you a version of the kingdom of Al-Andalus, although it already exists there is no woman leader, and in Spain is well known the phrase of Aixa the mother of Boabdil, the last king, her phrase: cry as a woman what you couldn't defend as a man. She may never have been a queen as such but she was very influential, she could be focused as a leader in attracting foreign cities to her kingdom, similar to Leonor of Aquitaine, and she could have an exclusive building, the Alcazar, similar to the building of the missions of Spain with an architecture similar to the wonder of the Alhambra.Thank you!
