The Damage Counter mod (+ ingame clock) works properly, showing a total number of damage in left top counter. Problem is that after installing this mod the number of damage dealt doesnt show/display over enemy ship after hitting it.
After uninstalling the mod, problem disapears and I can see the damage numbers displaying over enemy ships after a hit again. I tried redownloadign and reinstalling the mod/modpack but It didnt fix the problem.
