Atm using xvm, Scriptloader, YK and i can click on report details without any issues (close it, reopen it).
However i had this issue once in the past, when wg did something to notification center, but can't remember 100% what caused it.
(but i know it was one of the mods with notification center acress, ...there was some sort of conflict)
Now since wg touched notification center again with merit rewards.
Try removing mods that print stuff inside notification center ...idk stuff like: version checked, friends notification, session stuff,...whatever)
You should be able to narrow it down eventually.
Or simply avoid mods that modify battle result window, tech tree, notification center and blame it on wg for breaking stuff, again.
