In our case, it stuck right a way. Just put it there, noticed that it not where I wanted it to be, tried to take it out - nope. Ended up changing car.

Clarification for that bug, since original poster was little bit emotional:

Ok, just uninstalled Arma3, deleted it's folder, installed from the scratch. Now it's working

Same here, guys. Kinda dissapointed, cause I just bought Apex DLC to play co-op campain with friend. I checked cache twice and unsubscribed all mods.
