@JezuzLizard this post with the scripting reply is something i looked at about a year ago trying to figure out a fix and you just reminded me of it https://www.ugx-mods.com/forum/scripting/11/how-to-fix-wunderwaffe-glitch/11621/

@cheezkid26 Cool deal, for reference your friend should port forward 28960 and if you plan to run mods both of you need to have the mod installed before connecting.

Are you letting your Plutonium Launcher update? It should automatically re-download the unlockstats file into your players folder. [image: 9m6TE6S.png]

@RileyDumbass right click the pluto_t4_full_game torrent -> force recheck. After it reaches 100% (seeding) remove it from qbittorrent.

@HannesC Nevermind I used this https://forum.plutonium.pw/topic/9751/windowed-fullscreen-fixes-alt-tab-stupid-crashes Now I can open multiplayer but I can't open zombies

Make sure your gpu drivers are updated, also try alt tabbing out to the bootstrapper window, and writing r_fullscreen 0 and vid_restart in it.

When downloading a mod? Yeah make sure not to interrupt the download. However if you do somehow manage to interrupt it, don't try to join the server again, otherwise you'll crash. Delete the specific mod from %localappdata%/Plutonium/storage/t4/mods folder and connect to the server again, and wait for the download to finish.

if there multiplayer mods make sure they start with mp_

@ChosenUndead try windowed borderless
