Creator Response Clarification question with the museum

[Pieisflammable]

So me and my friends in our group's latest game had a grandpa goal that was fulfilling the museum. The museum is and correct me if I am wrong two different sides artifacts on the left and minerals on the right. Would the artifact question mark tile be able to be used on the left side only and the mineral question mark tiles on the right side only or could it be used anywhere since it says it can be used in any slot. They are saying it can be used on the other side but I am saying it could only be used on its respective side based on the symbol on the question mark. Any help or clarification would be appreciated !!!

The question mark artifacts / minerals can go into any space in the Museum. It is meant to be "wild" to help deal with the tough to fill spots. Hope this helps!
