High Valley Target is glitched on Missile Plant co-op mission

[davestovies]

So I'm currently working my way through the co-op missions and trying to get the collectables and for some reason my HVT just isn't appearing now during Missile Plant. He appeared but once I moved Sam towards the objective area the HVT name just disappeared from above the soldiers head and it's now re-appeared. I've restarted the checkpoint and now it just doesn't seem to spawn again. Super annoying seeing as Missile Plant is meant to be the worst mission to do split-screen with two controllers solo.
