Im gonna blogpost
For literally no reason at all my project for my room I have poured hours into just decided to fucking destroy my lightmap constantly. It was without rhyme or reason it kept shifting the light map uvs on some of the objects. I had a work around by double baking and essentially hoping it would only destroy some of them. It led to having half of the lightmap going unused though which is stupid. I was so distraught and about to give up on this project entirely because even starting a new project and copying everything over it still was borked.
I decided otherwise and started another new project this time reexporting everything from blender again. I am happy to say everything seems to be fine now, and im pretty sure I have gotten everything back in its place correctly.

TLDR: Come play connect 4 with me pls I haven't actually tried it with anyone else yet
