Hello, my axis settings somehow change after I slice a file, so it flips the part in the file 90 degree, witch wraps it out of proportion.

I made a post on reddit already, I'll paste what I wrote there on here and hope someone can help me asap.

Hello good folks, so earlier today I was trying to print a big mini for a friend of mine, since it was so big, I ended up laying it down (like on a bed) with the mini's lenght being down the X axis.

I put up all the supports, hollowed it out etc and got ready to slice it in chitubox, then I saved the file.

I tried to open the file once more, just to be sure before I started printing, and I got a error message saying "The file is to large, so only parts of the 3D model and all layers can be displayed". I googled it and saw this is a problem many have with the Photon, but it still works, so I put it on the USB stick and started printing, since it looked OK on the Photon.

Now, 6 hours later when the print is finished, it looks off. The mini is way more narrow than it should be, it looks like the Y axis have been compressed a lot, and I don't know why?

I gave something else a try, I wanted to put on a print before I went to bed, so I found these 3 prints on cults3D, and thingieverse.

This is how it looks before I start slicing it.

These are my settings

Then after I slice & save the file, I delete them from the "worktable" and open them again trough "open file" and it looks like this:

What can cause it to be this wrapped and not the same way i saved it?
