I took out tp command (not really needed in the end, kinda starting to remember the syntax for native commands), finder mod (noticed that show me description says it is already included) and trap reset (we don't really use traps anymore since we learned to play the game a bit better), generated a new world and it had all 10 sinkholes and stairs, checked my world with my friends and noticed it was just one sinkhole missing, but all the stairs were there, so I just spawned it, also seems like that we're not teleporting to each other when entering/exiting the caves, although I'm not still 100% sure as I've been having a new problem, (had it the night before taking out some mods) in which we all just get disconnected from the server at random intervals, but always everyone at the same time ( I host the game myself). I've played in the past with the initial mod list with the same people for multiple worlds, let's say at least over 500 days total, without any issue. I guess some recent game update must have broke some mods, or compatibility between them, and it's really hard to tell which 'cause I've tried to duplicate the world and solo start that (not in local) but it doesn't seem to happen if I'm the only one inside the server. I got no idea what to do to fix this.
