On the latest dev version, the server has stopped saving the ResearchAndDevelopment.txt file no matter what I do.

I tried renaming that file to ResearchAndDevelopment2.txt and it didn't generate a new one while re-joining the server.

Restarting the server has no effect on the issue.

Generating a Universe from my local DarkMultiPlayer "save" saves the file perfectly fine so the issue must be indeed on the server.

It looks like my profile was somehow corrupted as fully removing all traces of my player but the token made the system work again.
