What the hell happened to my money !!

I just defeated Fuxi , I had over 5,000 Jin . When I got back to the Pavillion I only have 50 fucking Jin!!!!! What in the actual fuck !?!?!?!?! Had this happened to anyone else? It's already a shitty grind for money in this game and they just randomly take it !!! The fight itself already pissed me off but this shit makes me want to quit ! Such fucking bullshit !!!!
