It’s what I’m getting each time I launch my server. 10 minutes ago it starts normally, but since I manage some config in sponge config folder I get this issue.
I see that comes from entity activation range. But in fact, I never modify the lines which are talking about that. The only ones I’ve touched, was the logs tracker possibility 
Somebody could help me please ?
EDIT: There is my crash log
To me it looks like Dynmap but I could be wrong
Ho ?! really ? because yes I’m in trouble with dynmap too, cause the command /dynmap abort every time (duplication of the command by a plugin it seems).
For me here the issue comes from Sponge itself and some world configuration no ?
Hmm I do know sponge did change up some of the world configuration aspects and I think I read somewhere recently that some parts of it are broken
@gravityfox He’s also using your Plugin, anything of yours wrong here?
@Darktilldawn you think about foxguard ?
Yeah He’s using Foxguard
and should be a reason of the dynmap issue or entityactivationrange ?
You said you never changed up the activation range so it shouldn’t be that. Send a pastebin of your SpongeConfig
the global.conf ? or each world.conf ?
Oooh you got separate worlds?
yes. Because I’m trying to create a Ressources world. and I’ erase all world folder and sponge config. The serveur launch good. But when I create a new one, the crash appears and then the server crash loop for the same reason as before.
The world is create by the mod simpledimensions because it can generate BOP worlds.
Hmm I’m out of my element here, so it’s coming down to the world management to me. Dynmap uses it, BOP uses it, and sponge controls it. So it might be the BOP causing it when creating a world? Could be an error in the way you write the individual world configs. I’ll let someone else put there chime in here
okay ! thanks to have tried help me
Okay, the issue is identify for one action. Indeed, it’s when I create a new dimension with the mod SimpleDimensions, with the BOP generator. It seems cause some problems with Dynmap, sponge and Pixelmon. But I absolutely don’t know why… 
If somebody could help me please
Pixelmon has some compatibility problems with Sponge. Just search “pixelmon” on the forums.
The issue comes form the generation of a BOP world with the mod SimpleDimensions. Since the sponge community released a plugin which can do the same thing of SD, no more crash happen.
Thanks all to have tried to help me.
