[Gate-users] cylindrical volume crash

[Bryan McIntosh]

Gene,

It looks like your simulation is crashing because you forgot to define
the size of the crystal before you attached it.  Set a height/radius
for it first, then any repeaters needed before you try to attach it to
a system.

Hope this solves your problem!
