I wanted to run Psi on my private machine for the sake of chunkloading, but when I put Psi in, the server crashes when starting. I've tested this with versions 17, 18 and 19.
Becouse I am still setting the server up I run it in VirtualBox on Linux Debian

here is crash report with other mods: http://pastebin.com/3ZgJWJpr

This should be closed. Also, @Vazkii you should put this in the issues.md or whatever the new template format is.
