Never seen this before but something somewhat similar happened to me in the London Streets map. I was walking near where one of the tanks comes through (it was the very begining of the match so it's going to be a while before the tank comes). I'm hanging on one of the walls that block the street off where out of no where, the wall explodes as if the tank went through it (which it didn't). I was laughing though as seeing the wall randomly explode for no reason was pretty funny, even though it killed me lol.
Happens a lot. It's like the glitch where the walls for Deathmatch are present on London Streets for some people even in Plunder. You can't go through, but people for whom the wall isn't there, run through like ghosts.
I suspect the wall is there for some, not for others.
I watched the area this time and no one picked up the RPG if the wall had been knocked down for others. I haven't had one game on Village where this hasn't happened since 1.17, I honestly believe it's completely broken now, at least when ever I'm playing. That said, I tried it in a custom game and it worked fine.
I've had the problem on London Streets too, and the Chateau wall that can be jumped through, but this has become way too common for me.
