Oh! Yay. I had not. I thought about going through the patch notes since the wiki is community-maintained, I just hadn't gotten around to it yet. You get a cookie (or other favorite snack) for doing the heavy lifting. Thank you!

After making my first world and starting a base, I realized that I didn't like the world seed and wanted to change some of my settings, so I created a new world. I wanted to move my base from the old world to the new one, but when I tried, I got the error in the screenshot. I'm sure it is a user error, but I have no idea what I've done wrong. Any suggestions? Game version 1.19.3 with a handful of QOL mods. I am using the commands from the wiki page; the exact command I typed was [/we mex base] (with the intended file name being base), but it spits out this error and does nothing. Using [/help we] spits out a list, but it does not include the export or import commands. The second screenshot shows my selection and the tool selected.
