OnEntity Death

Getting this error lately, no idea what's causing it as of yet:

25/12 16:27:16 | Failed to call hook 'OnEntityDeath' on plugin 'XLevels v1.0.5' (KeyNotFoundException: The given key was not present in the dictionary.)

Here's my config:

XLevels.json

Found the shutdown log:

[SERVER v1.0.20] Started as service
[SERVER v1.0.20] Running as service
[SERVER v1.0.20] Got Message: Ready
[SERVER v1.0.20] Got Message: Compile

[SERVER v1.0.20] Connection closed.
[SERVER v1.0.20] Shutdown

This appears to be a server host/pc side error.

Rooted out a few issues, the plugin is now stable on my end. The original error in this support request is still unfixed, but it's more a minor annoyance in console and a small lag than anything.

Changed Status from Pending to Closed

This was never fixed. Moved on to a different plugin for the time being.

Wow. I just saw the support section.

I didn't receive any notifications.

Yeah sorry man. When 'Guest' Closed this I just figured nobody gave a shit lol

Is there still a problem?

Changed Status from Closed to Pending

I think that first issue was coming up still when I stopped using the plugin. It was frequent enough to notice lag spikes happening during the moments it would come in. No idea what was causing it still. 
I started using a different plugin around that time for level up features and don't have this one installed anymore. That being said, when I get online tonight I'd be happy to put this back on and see if I can get more information for you!

-Might even have time during lunch - we'll see!

Okay. I will wait for more information from you.

If the error remains, I will look for methods to solve it.

My time: 17:21

Copy! It may be pretty late for you when I do get to this. Should be able to test in 6 hours! No rush!
