Animation Lock Glitch?

So I've had this happen a few times, and I've heard other people have it as well, I was wondering if there was a known cause/fix for it.
Yesterday during AR2 on the rampart/gear floor, I popped the gears like normal, and when I tried to engage I was engaged server side (I could see the dmg in the chatlog), but not on my client(I had Attack in the sub menu instead of the change target option) and I couldn't move or ws. I could use items and JAs, and change gear though it wouldnt blink or show the gear swap. Eventually I just used a RR and let myself die, and when I got up it was fine.

It was the first time I've seen it in salvage in a couple hundred runs, but I've seen it alot on PWs. so I'm assuming its because of the number of mobs on me(though training mobs I never have problems, so IDK..)

Nope :£

I know there's a way to force client side engagement to get around it, but I can't remember how.... sure someone will though

If you're getting spammed with animations, like a dozen gears attacking you, it won't change animations until there is a break in them. It's not really a bug or glitch. If you use command line for your WS, it should work like normal, but it could give you "must be engaged" if you try to select it from the menu.

If you use Gearswap, it bypasses the client's engagement requirement.

Well it doesn't seem like the normal lag you get when you try to engage, it lasts a few minutes instead of a couple seconds. It wouldn't be a problem if you could move, but if you aren't facing the mobs and you're the only melee/solo you're SOL.
For PWs, I have just been lucky enough to be facing him when it happens, and I'm forced to just auto attack until that form dies, and it fixes itself when it despawns.
