Upon using serrated strikes on skeletons in a spawner, it comes up with message "Hey sorry you cant PVP here" however doesnt come up while normally killing them only when you use your special. Recreated alot of times. I can still however kill the skeletons just the message comes up.
ehm. was anyone remotely near you ? as serrated strikes greatly increases the range and width of your normal attack and adds sweeping strike to it.. it can hit things like 2-3 blocks away this can also be triggered by ppl in vanish
This could have been your issue then. Serrated Strikes increases attack range meaning anyone within maybe 2-4 blocks of you could have been hit hence you receiving the, 'Hey, sorry you can't PvP here' message.
mcMMO issues will need to wait until we get the new mcMMO out. We are currently waiting on the new mcMMO to complete another major update related to configuration before we proceed with merging it into our server. It does however seem like this was a problem on your end.
