3 questions, thanks

[Gerald_Mei]

Excuse me. While I'm taking over the command of an old DS server which already exists years old, I found 3 issues. Maybe I can find some help here?

Issue 1:
"Error, cannot load plugin <condata.dll>" while loading plugins.

Issue 2:
"Error, cannot load plugin <event.dll>" while loading plugins.

Issue 3:
The “dont_eat" and "dont_rust" toggle in [CoreModule] for special base is not working any more. That base setted to "1" is still costing repair materials and food supplies.

I just took over this old server recently and don't know when and where these issues happened. And idea where should I start first?
Thanks a lot.
