when modeling in 2014 and then opening later in 2015?

We have run across some models that were modeled back early this year (in 2014), and now are just being run for the first time (opened up with 2015) and we have some crazy bend allowances that we are almost certain was not the number that was originally put in there.

we also had on person say that they drew a profile and extruded it for the base flange, and then when they opened in later in 2015 it was extruded the other direction.

Problem is I can't recreate these issues. we still have 2014 and 2015 licences at the moment, and i tried it with one that i was pretty sure had changed, and it worked fine.

Also want to point out, in my case this is a customer provided .stp file, that I brought in and used the insert bends feature.
