an then

Try it without reloading

same result. I start the server, no errors on console and the stats is -1 on the variables.

Like I said before, sometimes is the disease and other times is the Thirst. Some times happens the both show -1 and sometimes is anyone. but when I close my server, starts the thing again

both plugins are detecting the ScoreBoard Stats and registering the variables.

Could you send the complete log?

I solved the problem downgrading my version of ScoreboardStats to ScoreboardStats9.12. Now, there is no errors on console and all the variables are working all the time.

Thirst -1
Killstreak -1
Mob Kills -1

Can confirm this ones is broken. Are they updated to latest release?

for the latest release, Thirst and Disease are broken. The others I don't know. Like i said, I downgrade my version to 9.12 and both of them are working again.
