NullReferenceException help

[kampnkarl]

Hello, been getting a null reference exception error when another player joins my game. Any thoughts as to what it's about?

Was an error in the progression.xml, thanks though.

Was it caused by a mod or a corrupted file?

A Mod. In case you're looking for the same thing I'll give you the code. I tested changing base states with base_add and base_set, but neither are working for multiplayer. Both work just fine in singleplayer, and throw no errors or warnings.

Is the mod loaded on the server or just your machine?

Some mods can be server side only, some should be on both client and server.

 

[kampnkarl]

I have tried both client and server. Both cause the null reference.

Without a full log on Pastebin, there isn't a whole lot I can do. Instructions are Pinned, and have also been linked to in this thread.

It's all good, I found the problem.

What was the issue?

What was the issue?

If you are having an issue, it is best if you post your log files in pastebin.  Null referenced errors can mean lots of things, so troubleshooting your issue will require more details.

 

[kampnkarl]

What was the issue?

An issue with progression.xml. Editing base health and stamina via perk points was causing connection errors in multiplayer.
