If I have this plugin on my server, after an hour or two TruePVE stops working. It took me forever today to figure out why but when I take DynamicPVP off the server, TruePVE works fine.

Use the latest version of TruePVE.
If you still have the problem, let the TruePVE developers know.
DynamicPVP is just the API that calls TruePVE

I am using the latest version. I also made a post on TruePVE cause I didn't know which plugin would cause that but thank you for the response.
