Hi,
me and my friends have been using your mod on our private server, and some times when I try a new spell that i've made, they crash with this error :

crash-2019-02-01_19.24.12-client.txt

This crash was when I was spawning multiple circle in a sphere form :
crash-2019-02-01_19.00.06-client.txt

And for some reasons one of my friend instead of seeing multiple circles, he saw this

They have forge : forge-1.12.2-14.23.5.2809
And I have forge : forge-1.12.2-14.23.5.2796
We are using the version 2.1.5 of Random PSIdeas

Hope this help

fixed in 279dfba
