Landscape scale got messed up and is causing hitches / lag spikes

Hi, for the past couple of days I was noticing I get small hitches when navigating my landscape, and after a very long time of searching I found it is because my landscape scale somehow got set to 49, 49, 100.

I’m not sure how this happened at all, but I know it is the cause of the issue because the hitches go away if I reset it to 100, 100, 100 as it is intended to be. Unfortunately, of course this stretches my entire landscape in the X and Y axis to be twice as long as I designed it to be.

Is there any possible way to alter or apply the scale of the landscape while maintaining the work I’ve put into it? It’s not a huge landscape, at a resolution of 2017x2017, but took about 15 man-hours to get to it’s completed state. I’d hate to lose all of that progress. I’d appreciate any insight, thank you.
