Just learning this game with my friend, and I need some help with a turn. First play through for both of us.
Round 6, I placed two workers on Repair, and my opponent also placed 2 workers on repair. He went first and took both of the available face up repair cards. I had planned to pay 10 to look through the deck, but the interface did not allow it. It did not let me click the deck in any way at all. Was there a violation of the rules or was this a bug?
Here is the table. Repair begins at move 258. My trouble begins at move 271.

We had several actions in this game where we misunderstood the rules, so I really want to know if this was a rule issue. Any input would be helpful!

when you say two workers, was one of them an apprentice? or were both workers numbered?

because you have to have an apprentice there to do the deck search, and then remove that apprentice from the game permanantly.

Here are the rules for search from pg 14 of the rulebook.
Rulebook

Search: If an apprentice was assigned to the worker chip, players can pay a sum of 10 money and/or inspiration to look through the deck for a single card, looking only at the back of each card for either the instrument type, musical era, or patron type they desire. Take the first matching card found into hand, and return all other cards maintaining the same order. Sending an apprentice to fetch something specific takes time, so after the action is completed, including the location skill bonus, remove the apprentice used from the game, meaning they are no longer available to that player.

In order to be able to use search, you have to have a Worker + Apprentice assigned and being used.
At turn 271 in your linked game, you've just got worker 4 (and then worker 1) to use, so you can't activate the Search funciton.
