Here another thread about that campaign:
[You must be registered and logged in to see this link.]Clients may crash in custom campaigns when they are using certain addons.
I've disabled spawn uncommon infected for that campaign.
Maybe that helps.
I further could disabled:
- csm
- CSS weapon unlock
- melee weapons which are not in the map
All that could help to get a custom campaign running better.
Very often problems are caused because of precached models.
Sometimes the custom map is so huge that additional precaches done by plugins will cause problems.
And the most common plugins which need precache are:
- spawn uncommon infected
- csm
- CSS weapon unlock
- melee spawn control
