Problem with my save file!!

Hey guys, I've spent over 30 hours on this park. I've used various mods, including a new species mod, different decoration pieces, and a new fence system. This morning, when I clicked on my save file, the loading screen appeared, but it just kept loading indefinitely. I didn't encounter any crashes, and all my mods are functioning properly on other save files. Do you guys think it's because I've used too many mods for decoration? I have placed lots of pieces in the park
