Too many experimental blocks loading error
I play on xbox series x (If that matters)
So ive been working on a build for a couple of days in one of my creative worlds, i've been logging in and out with no problem but for some reason now without warning I get an error when I try to load the world. The error reads "Saved world exceeds experimental block limit, cannot load world" Ive looked everywhere online and nothing came up about this issue, I am on experimental mode and the only mod I have on the save is the xbox speed mod. Everything else is vannila and in total the builds in the world dont take up more than 200,000 PCU. I do have the PCU limit at 500,000 currently. I just want to know if theres anything I can do to fix this issue or is my world gone for good?
