Yeah i can agree on ship contours and (Dmg recived and Dmg done) also isn't working for me too. Any mod that's related to the UI especially.
I have opened my own thread btw.
Prior to 7.7, i have no issues with any mods even when my client is undetected by the modpack. It has been that way since update 7.0.
Glad to know that I am not the only one facing issues.
I believe the introduction of UI scaling on 7.8 is the cause of the issue. Hope you can look into this further aslain and come up with something.
