Reimported Mesh Location is different

Hey! I’ve been trying to optimise my meshes by combining multiple meshes’ UV Maps into one to save on texture maps. However, upon reimporting my meshes, they seem to reappear in a different location. I made sure to not change its origin in blender 2.8 so that shouldn’t be the issue. Anyone knows why this might be happening and if so, how to fix it? Thanks in advance.

Here’s a link to a video of it happening.

Try to export you mesh as an OBJ file, mabe that will fix it.

If not, tell me and I will do me best to help you
