There are real concerns that people are using evo's as a guide in solo.
This is in my humble opinion not something that should be working.
If people say this is not happening then there is no problem blocking this.
Solo solutions should really be solo.
An easy fix to this problem would be, to make a solo immediately go evo if you load a guide from an evo.
This is how I think it should work.
People in groups would still be able to compare their solution to an evo, and work on their saved solo after inspecting the differences but no longer be able to use bands to the guide of the evo.
