different beta versions?

If different people are working with different versions of the beta (i.e. x.15 vs. x.17), will that make things wonky?

 

There are some known issues with 15 which are fixed in 17, so I'd strongly encourage updates. In general, the only direct issue that might occur between the two is being forced to update the ProjectVersion.txt contents every time (i.e. it'll change between b15 and b17 every time a different versioned editor opens the project).
