Fuse version 1.2.1 (build 13974)
Mac OSX 10.13

When I run “fuse import mobile.sketch” I receive the following error

fuse: unhandled exception: Could not load type ‘Outracks.Fuse.Import.ImportOperation’ from assembly ‘Fuse, Version=1.2.0.0, Culture=neutral, PublicKeyToken=null’.

What Sketch version are you using? Could you provide the sketch file that has the problem?
