Where exactly can I find that script? Is there even one? I am not a big fan of ingame messages that is why I want to get rid of that.

Refresh my memory, when do these pop up?

When you get disease you get a message saying, "You have contracted X." I assume the op wants them removed to add a bit of difficulty to that aspect of the game.

It's a GMST sMagicContractDisease. You might try to replace it with an empty line, but I'm not sure if it'd suppress a blank box appearing when you contract a disease. Issuing a message is hardcoded and not a part of the script, so you can't disable it totally. Unless you plead to MCP authors, maybe.

Thanks, will have to try that out.
