My hammer won't load what I make on my map

I am having a problem with my hammer where it wont load what i edit on my map. I’ve seen a lot of people with this problem. It seems to be spamming to many light styles on a face

It’s because the map isn’t compiling properly so it falls back onto the last successfully compiled version of the map, see what you changed since last time it worked and remove it bit by bit until it works.

Thanks! :smiley: ill try that
