Bug

Hello, I bought clay bricks for my guild's quest on this land: https://nomstead.com/kanin. I bought them once, and 7.5 gold was deducted, but I didn't receive the bricks. I bought them again, and once again, gold was deducted, but the bricks never arrived. I went to other lands and bought 50 bricks, which I then added to the quest. In total, I bought 150 bricks. I donated 50 to the guild, 50 are already in my inventory, but I haven't received the other 50. I think this is a bug that needs to be fixed. Thanks.
