The bundle files does not get loaded on first load, but when refreshed they get loaded.

I have installed latest NuGet package of LigerShark.WebOptimizer.Core i.e. 3.0.477.

There are same issues listed which are still open and no solution till now.

This is urgent and any help would be much appreciated.
