Turrets and cameras not saving

So, I created a new world, with turrets, ceiling turrets and cameras. When I save and load the world, they have disappeared. All other things (NPC, props, etc) have been saved.

How do I make sure they stay? They’re essential for my maps.

Thanks.

Update: Striders, helicopters (both the gunship and the other), shield scanners (those who carry the mines) and all stuff from my ep2 addon (hunters, zombine and antlion workers) aren’t saved at all. I tried removing the ep2 addon, it still doesn’t save.

Does anyone have experienced the same problem?

Same problem here.

Ok. When I migrated to gmod 13, I copy/pasted all my old gmod addons, textures and models. Have you done that? I wonder if the problem was caused by copying my old addons, because nobody except you seems to have the same problem.

I’m currently redownloading gmod, I’ll see if it works.

After reinstalling gmod, it still doesn’t save turrets and other things. :frowning:

Anyone?
