HI Blood asp, thanks for the amazing work!
I found that there`s might be a bug involving the fusion reactor and the new achievement system.
If the option EnableAchievements = false, the fusion reactor will work in a strange state.
Or if do not disable the achievements system, the server side will receive message spams.
More details I have posted on the bugreports on Github
