Sorry everyone, I goofed.

It appears that something has changed (or I did it incorrectly to begin with) when we made the IllegalStack 2.8 update. There was some code that uses Protocollib, this code when paired with Protocollib 5 resulted in my plugin breaking combat a bit.
**Players were unable to land critical hits or do sweeping edge damage among other things.
I regret this has happened and for any inconvenience (player rage) this may have caused and for the delay in recognizing this was my fault rather than ProtocolLib's!

Please update your IllegalStack to version 2.9 (or greater) and use protocollib 5 (or greater)


*EDIT* also in this update new features!
1) This update should fix the bubble column exploit dealing with arrows/snowballs/etc. There is no great way to detect items floating in a bubble column in regular spigot so please let me know if there are any issues.

2) added a protection / notification to protect against the string dupe.

3) fixed a couple of protections that would omit themselves from the DisableInWorlds list, and adopted a better system that should greatly simplify the way this is checked and result in fewer protections slipping through the cracks.
