Describe the bug

Minecraft 1.18.2
Patchouli 1.18.2-66
Pneumaticcraft Repressurized 1.18.2-3.1.4-68

When i start the Forge Server, some red "errors" are showing up in the console (the server starts), which say the following:

Crash log

No response

Checking through them, these warnings are all harmless.

• The Drone Interface recipe suggests you don't have CC:Tweaked installed? This is a forge conditional recipe so I'm surprised it warns. But it won't cause any problems.
• The second warning (rejected vanilla connections) isn't a pneumaticcraft issue at all. A vanilla client tried to connect to your modded server and (correctly) got rejected, by multiple network channels.
• The last two warnings are also harmless and can be ignored. See https://forums.minecraftforge.net/topic/88313-could-not-serialize/ for more information.
