NexEngine is not available on a supported website. You could have figured that out in less than 5 minutes
Seemed to take you longer than 5 minutes bud

Thanks for your time.

What do you mean with "built in"?
That plugin doesn't contain NexEngine.My bad with the way I worded it. It isn't built in, but the plugin requires NexEngine, which is also not available on Aternos for whatever reason.
Image of what pops up when I suggest it attached.

Doesn't work, says the mod is invalid because of NexEngine, a built in plugin.

This was one of the greatest plugins on this site in which I used in almost every one of my servers, today I check if it is there and nope, doesn't show up. I really need to know if they got rid of it as one of my servers that I spent a majority of last summer on depends on this plugin for the items, and without it it is going to break in every regard.
This could be really bad so any info on EE would be appreciated.
