Hey, I'm sorry that you faced these issues, however, I was not able to replicate the 1st issue you specified on my test server, and you didn't really explain the packets exploit you could've found so no idea about that. Perhaps we could talk on discord (
https://discord.gg/mGwymZWGUf) and you could explain further so that I could replicate your issues and get a better understanding about them and fix them? Thanks.
