disappearing point entities

yes I did a search but no one else seems to have this. Just similar things but with props

NOTE: I have found a way to deal with this, I just wondered if anyone knew why this happened + any way of stopping it from happening again

After loading up my map all the point entities (inc the player_start) dissapeared. Without actually noticing this I did some stuff with func_breakables and compiled and tested it in-game. It said I had no player start so it spawned me in the skybox.

So I when back to the map and discover the no point_entities problem. I when to Map, Entity report and they (said point entites) showed up. I clicked go to and I got a dotted outline of where they where supposed to be.

I fixed this by deleting (via the entity report) and replacing the missing entities. But what if this happens again when there a lot of point entities? (So far theres just the bits for a pair of ropes, an rpg, a player start and a crossbow) Can it be prevented?

I can't give the compile log though. Sorry

Ah. Have just discovered a leak, but I've never heard of those wrecking up point entities

Are you sure you didn't have them hidden when you compiled? You may
have accidentally unchecked the entities vis group on the vis group
panel, and if you compiled after doing this then they would be ignored.
They would still show up on the entity report if you had the "include
hidden objects" checkbox selected, and you would still be able to go to
them from this I guess.

In Worldcraft they still showed up after a compile, visible or no

EDIT: Fortunately the rope stuff hasn't been replaced so I'll check with that.

Also: Its rather unlikely that that would happen

Well I accidentally had left some of my entities invisible in hammer
and compiled, and found them to be missing in game, so it definately
isn't the case anymore. I find that useful though to be honest, you can
put details away into vis groups and compile without them if you want
to test out the flow of your map without clutter and so on.

Suprisingly enough, that was the problem! Stupid me looking for visgroup flag in the object properties...
