Does it actually show a flux dissipation value in the refit screen?
Yep all those stats are in that screen. total dissipation etc all look normal i used ron's editor to fill out the ship stats and etc and copy and pasted those from a working ship (remembering to change the ship #, id, name etc).
so the only thing i think it can be is the ship file itself, and i having a bad ship editor crash day trying to do literally anything.
Yup finally redid the entire ship file put it and boom venting again, so dunno wth was wrong with it or how the editor skrewed it up, but if you get that happening try redoing the file from scratch something went wrong, even if the game thinks it is fine.
