Please send me your config, and the files contained in the "/oxide/data/Trivia" folder

And it very well could be something wrong with your better chat.  We are running this on 7 servers right now with 2k players per week and have Trivia on 5 minute intervals and have not had a single error.

But I will still gladly try to help you figure it out.   If you'd like, I can take a look at your better chat config too.  I have used better chat for 5+ years on my servers.

Also, if you are able to, set Trivia to debug mode (option in your config) and try to re-create the error.  It will give us a ton of useful info into tracking down the problem.  Could be as simple as a bad configuration JSON or something.

Yeah was something wrong for sure...

Couple times i deleted data and config files. And now its seems all working.

Feels like this data file dont like to be edited manually... Im sorry maybe i was to early posted this error post. I will take a bit more time to figure out. a bit strange with questions.. for example if you have only 1, 2, 3, 4, questions, and you manually delete question 4, then reload plugin, and that 4 question is still on the cast, even when its no longer in data file.

To edit data files you need to completely unload the plugin first.  Do your editing, and then reload the plugin.  If you do not do that, the data will just be resaved

Changed Status from Pending to Not a Bug

Changed Fixed In to 2.0.130

Some times plugin just not working. check print screen. even player give right answer, it wont count....
