Server Crash on explosions?

Hey guys,
I have some problems using SpongeVanilla…
My server shows me following error, when a creeper / tnt block explodes:

I’m running my own plugins (on this server) too, but I cant see a line displaying, that there is a problem with any of my plugins…

Make sure you’re running the correct versions. The forge version should match the one that’s on the sponge jar.

Are you running any mods as well?

Sorry, but I do not run forge…

I wouldn’t recommend using SpongeVanilla yet. Just use SpongeForge. Clients don’t need forge to connect to it, so it’ll work all the same.

I know, in the past I used SpongeForge, but I was so happy to move to the vanilla version :slight_smile:
Hmm kinda sucks, but I think I can’t do anything against it, haha …

The latest SpongeVanilla build should fix this issue.
