I just experienced a bug that when I rejoined the server, it reset my progress to where I had begun during my last play session. My Dragonite lost 15 levels, and I lost everything in my inventory. I also lost 5 XP potions that I had bought earlier during my previous play session. Anything I placed down was saved, however. This bug only happened in my inventory. It happened at 6:54 PM Monday, November 19th, 2018. It happened on Poke Survival Server: 1.
