Anyone have any idea what this means?
The first errors in the log seem to indlicate that there is something about your InventorySystem which the weaver does not like. Those first error messages may have more specifics on which code is invalid.
After commenting out the code, the editor went back to normal. Thank you, that was a silly question. Still don't know why the weaver doesn't like my code though,
I think it had to do with Networking a List<>,
Excellent, glad you found the problem.
Look into Networked Collections in the online manual, if that isn't what you are using as a reference already.
