Fair warning, I'm talking out of my ass and it's 4 in the morning so whatever I say could be relevant or complete garbage, please take it with a grain of salt.
Ahem. With the mini-dump it could be a pretty big range of things like no shield mesh or whatever it's called, we'll refer to it as shiny bubble for I'm simplistic purposes. the game reads a shield, the fighter has a shield, but it's not displayign a shield so that might be where it breaks.
There could also be something not edited that needed editing, it could be reading"oh this unit has a shield" then while looking into another file for like the damage or something to be applied to such and such unit "wait, ashield NEVER" break.......again it's 4am
Then again it could be a Technology issue with upgrades in sec shields, did you research any upgrades? and if so what kind of tech was involved before/during the break. Also, my own opinion, if you do get this working, do you think you could make it a tech allong the shielding branch to add shields to the fighters? Be it late, early , or mid game is up to you but I think about mid would make things interesting without making it too late to be o any real use.
Or, now here's what i believe, your computer feels violated for you touching it's "hidden files" without asking and is rejecting you because it refuses anymore shame....or something *sips coffee* anyway, SHAMELESS BUMP
Maybe someone with real experience and with a heightened sense of cognitive awareness will be allong some time soon since this is at the top of the list now, cause I'm kinda hopping you get my swarms of fighters polished and shiny in their own little bubbles, Keep at it, I look forward to it.
