live reload on multiple files not workin in version 0.4.0

[EvertVerboven]

In version 0.3.2 live reload worked if you had multiple files
for example:

• App.elm
• Main.elm
• Model.elm
• View.elm

Version 0.3.2 watched all files and when changes where made live recompiled, version 0.4.0 only watches the file with filename Main.elm

elm -v 0.18.0
node -v 6.9.1
