I have a minecraft 1.16.5 mod server with my friend, I have a very serious problem, which has bothered me a lot and I am really frustrated, we were playing normally, when out of nowhere the game became peaceful and it seemed strange to us, I changed the difficulty it hard again but when I hit done, nothing changed, I saw that it had stayed in peaceful and does not want to change, we have changed and eliminated several mods to see if it could be one, but it did not change, I tried in a backup world and locked the difficulty on hard, but when I exited the settings menu and came back, I found myself with the annoyance that I was on Pacific!!! Guys, please I ask for your help, I would greatly appreciate your help. This problem ruined a server that I had planned and that took a while to create
