npm package destroyed

[benjamin79]

Strage thing happened. I just added a html dropdown. On rebuild i got: Can't find npm module 'gm'.
But i never removed it. Then removing and adding it back again to package.json solved the error.

I know, not much info i can give. And i can´t reproduce it. But without any change that should´t happen.

I happend the second time now. The first some months ago.

I thought i post it so if others might experience the same we can make out a possible cause.

thanks
