I loaded a blend file for the model im trying to convert aaaaaand this happened…

WHY did that happen???

Is that a .blend file or a file that has been converted or imported?
If a .blend, was it made with add-ons you don’t have, or with a different version?

It was 2.80 the current one. I was working on the model and saved it. I went back to try to work on it some more and this is what happened.

So am I the first one to experience something like htis?

Hi there welcome to BA!
It might be that you did a lot of work without applying the transformations. It should not happen like this but it may be the cause.

I dont know how to apply transformations…I never had to do that before until 2.80
