[BUG] I downloaded the SMBX 1.3 config pack, then I patched it...

[Bonnies]

Okay, so I downloaded the latest dev build of PGE! When I went to install the SMBX 1.3 config pack, the game had a "Legacy Configuration Package" error. I downloaded the patch and replaced the old files with the new ones, and now, whenever I try to launch the PGE Editor, it'll start, but I can't make a level because some items are missing!

Try re-downloading the configs from here

One note why you still have errors with patch: there are added some set of images: there are added a dummy elements - a hidden blocks, BGO's NPC's, tiles, paths, levels, sceneries. There are wasn't used in legacy SMBX, but internally there are has reserved slots, and there are can be used for a custom stuff. So, Yoshi021 pointed right place to take a laboratory-compatible config packs. Anyway, I just updated links on laboratory page to let people take right links to dev builds.
