Description of the bug

I've had a Saturn 3 for a year and I've used UVTools on pretty much every single file I have printed and it always worked flawlessly, yesterday I bought a Saturn 4 Ultra and trouble started.
When I print a file without going through UV Tools, it works, but after removing islands, suction cups, setting exposures, etc...I get this:

(the normal exposure is that high because my first thought was underexposure)

I've tried to-reslice and even using a completely different model and the result was the same. After a bunch of failed attempts I decided to skip using UVTools and voila it worked, then I tried that first model without UVTools and it worked as well.
So without any doubt it's happening because of UVTools, why specifically or which feature I'm not sure. This afternoon I'll try to just open the sliced file on UVTools and save it without modifying a single thing.
If it works, I'll try only removing the islands and so on until I find the exact cause

How to reproduce

  1. slice file for saturn 4 ultra
  2. open on UVTools
  3. do what UVTool does
  4. print a mess
