How do you get auto saves to work in a custom made map. I can't get mine to work.

I have created a brush which has the trigger texture, and is an entity of trigger_autosave. Health must be above 99 and danger level must be 3 seconds without taking damage.

The game seems to save the file when i pass through the entity and appears in my save games list, however the game is then unable to load the file, neither automaticly nor manually if i try and load it.

Help

I've made a brush which has the trigger texture, used Ctrl-T and choose Trigger_autosave.

Further I didn't do anything, and didn't test it that good. But I do know that when I die, I appear there.

nope, still doesn't work on my map. I have a feeling it's something to do with my map, rather than the fact that i haven't set it up properly. Anything that might cause this?

It's really bugging me, as i might not be able to finish my map for the comp without this.
