Double sanity drain with normal characters in Multiplayer

Hello @Blizi, welcome to the forums. There's a few questions I think you should cross off first:

• Are you playing mod characters?
• Does it also happen when you are playing with default characters (like Wilson, Willow, Wendy etc.)?
• Is the server modded? If yes, what mods are your running?
• Does it also happen when you play as client on somebody else's server?

I'd recommend for you to verify the integrity of the game cache, wouldn't hurt.

No modded characters used, yes it happens to them a lot.

Server is not modded

It solely happens on any server that is not my own, on modded ones the sanity drain isn't there. When there is no mods on any server besides mine, sanity spikes down hard, I could enter full insanity by dusk.
