(Don't know if I missed a post about it, but here goes)
Something I noticed since 7B10, is that mods randomly get "un-highlighted" (its name shown in white text when using it and thus the page no longer "focus" on it) in both the Mods Screen and the Test Mods screen.
1st screenshot: Selected XF Cargo Mod
2nd screenshot: Its highlighted in the Mods screen
3rd screenshot: Selected a different mod (Rockspecial in this case)
4th screenshot: Went back and selected the XF Cargo again
5th screenshot: The mod is no longer highlighted
6th screenshot: Went back to the Rockspecial and it is now highlighted but not the other mod
This happens with any mod but seems random as it sometimes work. Dunno what causes it or if its just my LFS doing shenanigans
