Would you be able to tell me a bit more information about this error. How many times were you getting it? Was it only on a certain item? Were you in a clan or not?

Hi I'm the admin of the server was not me getting the error I just noticed it in my console. I received a few time consciously until I reload the plugin, then it stops and then starts again. Not sure if players were busy researching at that moment in time but I had 50+ people on. Hope that helps

After some testing I narrowed down the problem and have updated the plugin with the fix. Please download the latest version of the plugin and hopefully you shouldn't experience this error any more.

Thx will test and give you feedback. Thx for the nice mod
