They have been put back to the usual location because the Museum is not returning for 2026. The 75th Anniversary Museum was for the 2025 season.
Returning the photo op back to their original location keeps them in the area suited for them next to Jolly Buccaneer and does not indicate anything else at this time
2026 will likely not have any major investments as they still have to finish Frontier Falls & see return in investment on that project

(And if such a large investment was to return, they would have been teasing by now)
