It's not a huge deal, just a little annoying because I figured it was something wrong on my end. Good to know, thanks for the help! - By the way, what in the logs told you what was wrong? I just don't want to come crying and annoying mod makers every time something goes wrong.
Update: I moved all my mods out of my gamedata folder, launched the game and moved them back in, relaunched the game, and that fixed it for some reason even though I didn't reinstall anything. Looks like Reviva wasn't initializing properly until I did that for unknown reasons. Weird.
Update 2: That fixed the HUD in the inline mk2 cockpit, but not the mk1 inline cockpit with the MAS+DE IVA or the DE only IVA. The MAS MFD also does not work in the mk1 cockpit. I am generally confused. Re-initializing also did not fix anything this time
