I recently added Bit-defender to my system, and now i'm having a bunch of issues ,ranging from the server not being able to save to the void dimension crashing the server, i'm not sure which part of the antivirus is doing this.
I have looked for a while now and i'm still not sure

Every time i try to warp via command(/home,/warp) to the void world it gives me ''an unexpected error has occured''
The void cake does not work either

this crash occured when another player tried to go to his void island via /warp
Crashlog: https://pastebin.com/1CffimWq

It seems the void dimentions does not want to be loaded whatsoever

I have loaded the world in singleplayer and everything works exactly as it should, so the issue somehow comes from the server, no idea what's happening here

Edit: i managed to fix the saving issue, but the dimention 119 (void world) still doesnt want to load whatsoever and the server crashes if i somehow try to teleport there

Modpack Version 1.2.1
Windows 10
Bit-defender Total Security

Check #faq in discord for a description of how to fix the voidworld thing (it's known). The saving problem is unrelated.

Based on the messages in the console, the void world was previously loading, which is distinct from the issue causing it to never load in the first place that RundownRhino is referring to.

After installing the antivirus software, your server files got corrupted. Unfortunately I think your antivirus is at fault here and there's not really anything we can do about that. Sometimes the heuristics they use result in false-positive detections of programs. You'd have to consult your antivirus documentation to find out if you can tell it to ignore your server files in the future.

All I can recommend is to restore from a recent server backup. You can customize the automated server backups feature to create a set of rolling backups at comfortably frequent intervals so you can minimize losses in the event of a problem.
