the new update is spamming chat with every kill as you get a item and skull.
but no item or skull is received.

config.txt

also get a NPE error :(
NPE_error.txt

Please text v5.5.4

What ever you did in 5.5.4 fixed the NPE error but still getting the spam on every kill.
Noticed skull is only received when the blue text is shown.

but this (you got a "mob" skull and iron ingot) spams on every kill. its not isolated to 1 mob I'v killed every mob type to test it.

only thing im questioning here is your configs example area at the top. I see a string cmd for pex. is the new update dependent on pex permissions to function correctly?
if that is the case i dont use pex, i use luckperms.

Its not a permission problem. Could you please post your config.yml ? (on Pastebin.com)

You get this message because "message" tells so. You need to clear the text.

message: ''

for all mobs, or set the text to whatever you want.

thank you should let every one know with version 5.5.4 they need to remove that message line to prevent the spamming :)

Well as of 5.5.0 I announced that you had to review the messages :-)

In V5.5.5 i have decided to make a better message. The first one was bad. I agree. It was stupid to convert an exsting message into that field.

its cool i rather help find the issues and test solutions rather then cry and complain, lol. any ways i found that the npe error only happens if you attempt to change the config and do "mh reload" in console. but if i do a full server stop then start. i dont get the npe error :)

Im very happy that you helped! Its very time consuming to do the testing, and I spend a lot of time on my test-server instead of my real server (mc.lindegaard.one) although a handful of server owners help me with the testing.

When somebody report a NPE error or anyother error I always try to solve it. And I dont delete the ticket until is is solved, (or if the player who reported the issue stops responding)

Your should always create a ticket if you get an NPE error. I will always try to solve it. NPE errors are typically not that hard to solve.

Thank for you help.
