Had same thing happen when in Light zone trying to claim supply drop, theres a container in the middle of the street with the portaloos in a row and the cover on top, I vaulted the cover and dropped inside the container, game picked it up and re-spawned me, lost the crates though because I had re-spawned though.
The same thing happened to me last night.
I was standing atop one of the packages the team was supposed to mark covered against the spawn building. I attempted to jump/roll out of cover and fell between the package and the building. A subsequent roll caused me to enter the building. No doors functioned as exits for me. Had to quit & return.
