My server is supposed to be using a custom modpack I'm making, but I've found out it crashes even without any mods and only Forge installed.

I'm using Forge 14.23.5.2836 (same error occurs on 2835) on Minecraft 1.12.2.

The crash occurs only when at least one player is on the server, and happens at any time during exploration or standing still.

Here's the crash-report:

Update Forge.

This is fixed in 2836.

Some tips:

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

4.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

Hello, same problem for me, my server crash many times during games and crash many times a row ( 2 to 3 times yesterday).

I don't think this crash is generated by mods because it works correctly locally.

 

Crash-report : (for anonymity i remove players names)
