I'm not saying this is your issue, but using the same key tends to cause a bit of a hiccup for most players. It also leads to the shot being slightly delayed as it doesn't go until the button is released. Try assigning it to something else and see if it clears up your issue. If not, you can always change it back.
Loaded #03 with Windows Defender disabled, Battle Hits still not showing in the menu.
Aslain's Contour Panel (Arab) not showing now either.

I had a similar issue on my first game where it appeared to lock up after it was over but it did eventually close. The timing was around the same time as the after battle music ended but guess that was probably coincidental.

Unable to reproduce after updating to .4
Suspect it might be related to specific tank played earlier in the day. Will monitor again tomorrow and update if seen again.
