I was playing with my friends when all of a sudden the server crashed after someone threw a grenade.
I don't know if I was just extremely unlucky or if this is a more common issue but it was certainly not the first grenade we threw. I'll keep investigating when I have the time. Hope this can be resolved quickly ;)

Here is the error:

[14:27:45 INFO]: Stopping server

I believe this has been patched already, let me know if it happens after next release.
Thanks for reporting ;)

Awesome but may you send me a version where it's supposedly fixed? Like I said, since I'm playing on a server I don't want it to crash all the time because we are using grenades.

Thanks a lot!

The current working version is not very stable at all, I'd reccomend going back to 1.48 until we release another version.
It should only be a few weeks hopefully.
