I have reported in-game, but given the previous thread is (over) 2 years old and it’s still a thing, well.
I don’t trust in-game bug reporting much as there is no public repository, voting, closure status, nothing. In this case it’s obvious that nobody cared.
Yes, I can abandon these, but it’s just bad. 15-20 minutes of my time wasted for absolute literal nothing. No xp, no loot, no rewards.
Just delete the feature if you so don’t care, please.
Well there’s also the US Bug Report forum if you prefer that, but if I can give you a penny of my thoughts, you don’t receive an answer there either though there’s the possibility of more players to chime in and sometimes I pull solutions from it.
There’s a guide on how to do so in my link below:
Not sure I can access the US forums, but it’s no biggie. I’m sure the CS will casually see this thread, at least the title.
(I have no issue with mobs on the roof, we can fly in WoD now. Only the spawns inside walls that cannot be targeted.)
I do use the in-game report sort of frequently in hopes of helping fixes, I just generally find it a bit of a black hole. It’s also suspiciously fast, when pressing submit 
though I could use a sniffer to verify whether it’s doing anything. 
The thing about this specific thing, I don’t even find invasions particularly interesting, it’s just the game shovels them down my throat, so I do them, but then they are all bugged. I don’t see any reason for it to break over the years, so I have to assume the alliance garrison was always broken. Or there is an internal issue with it, the game thinking it’s a level 2 garrison (level 3 required player level 98 after all) - when a friend invited me to her garrison to show off her decoration, it changed to some standard garrison that wasn’t hers. Since the orcs got stuck in the outside wall towers, which is absolute deterministic and standard, not some building I placed.
Anyway, that was just rambling. 
I could shorten this but maybe there are bits of info that could be useful, just in case it isn’t a black hole!
