So, a chain of events.
I was playing on Kowakujō directed, and my internet cut out so the game crashed or whatever.
I restart the game and start a new match on Rex Infernus directed and play for a while.
I was spinning the box a lot to get the raygun mk2 but got that weird olympia with a name. I'd never seen that before, so I paused the game to Google it, found out it's an ultra-rarity gun I guess.
Later, still spinning for the mk2, I get a second ultra-rare gun, the miserable bastille I think. I pause to Google that one too.
I run out of pause time, and the game auto exits, and I hadn't finished the round where I got the bastille gun so I knew that was gone.
I quickly reload into the match, but the Kowakujō loading screen shows up, and I'm super confused.
It finished loading and I start on round 12 with basically the whole loadout I had before the pause time ran out, minus the bastille, then I record with my phone and thats the video attached.
I played for a while, the guns worked perfectly fine, minus a thing with the wardens guns, the dual-wield things. I was able to pack-a-punch the guns, and they got the Kowakujō PaP camo, and I could use the ammo caches like normal.
The only thing that didnt work was the cyclone charge shot that the wardens guns get after PaP. It could charge and shoot, but no little tornado would be made.
Dunno if this is a known thing or not, but I was baffled. Also, first post here, so im not totally sure if im doing this right.
TL;DR: I accidentally got Rex Infernus exclusive weapons on Kowakujō via an internet disconnect bug I think.
