Player Count Incorrect and showing non-connected players on Minecraft Java Edition (Forge) Instance (Could be on other games too but I host java)

Operating System

Ubuntu 24.04.2

AMP Version and Build Date

2.6.0.12 - 24/02/2025

AMP Release Stream

Mainline

I confirm that

• I have searched for an existing bug report for this issue.
• I am using the latest available version of AMP.
• my operating system is up-to-date.

Intended Action

View player list, go to the console and see who is connected

Expected Behaviour

Show 0 players (as no one is playing) with no names in the console tab or anywhere else.

Actual Behaviour

Sometimes (mostly) shows 1/20 with a name of a player that is not playing on the player list in console. (Proven by the fact that I execute /list and it says there are 0/20 players online AND that same friend went to sleep)

Reproduction

When installing AMP you set up the forge server using some tutorials and play with your friends.
It sometimes shows a random player connected. (I looked into it and I have NO IDEA why this is happening and how I can reproduce it, the whole panel is sometimes kinda broken).

Fairly common due to bots trying to join whitelisted servers or mods that change the join/quit messages.
Restarting the MC server should clear it out, and if not you can stop/start it from the main panel.
Just a visual thing though, nothing to actually worry about.

The mainpage has a refresh button, i've found that it will clear out non-existing users and also show users who aren't currently showing up in the user list.

Good point yeah, the list has a bug where it doesn't update in real time, which might toss some of the random names to the curb if AMP did manage to catch the disconnect message
