Making static entities collide with player

[Exostalker]

If you don't need them to be disabled or have any special properties, then don't make entities out of them.

By "I made new static rocks" I mean I took rock entities and with the entity to static tutorial I converted them to static. Sorry I was writing fast so it wasn't clearly written...

But now I just noticed one thing. I copied the entity rocks, the ones that weren't converted, and replaced the new static ones with the old entity rocks whcih would have to jump out of each other. And nothing changed. My guess would be that the game doesn't load the new models, or maybe the map doesn't - because whenever I change those models, they don't change a bit in game - I can still go through them. So maybe there is some kind of model cache or something? Map cache isn't saved, so it shouldn't be the problem.
Maybe the map doesn't recognise that models have been changed? That would mean that I need to recreate all those rocks again?
