The latest update to Conflict has made a change to vehicle depots such that only one vehicle can spawn at a time. A second vehicle cannot be spawned until the first vehicle is removed from the vehicle spawn point. If you try to do this, you will get greyed out vehicle spawn options where they are "blocked".

Prior to the latest update, the next vehicle would spawn into an empty space near the first vehicle. I always found this worked quite well and never had any issues with it.

This change slows down spawning vehicles a lot. Sometimes when it is not blocked you get a blocked message. If another player is moving across the spawn location or standing there, then its blocked (which is great fun for trolls and griefers). You can get many players crowding around the vehicle spawn waiting to spawn a vehicle. The longer it takes and the more frustrating it gets the more the depot gets blocked. A vehicle gets spawned and no one knows who "owns" it causing more issues.

Sometimes a spawned vehicle gets stuck or damaged meaning that the vehicle depot needs to be deleted and rebuilt elsewhere. Even if there is a single item (like a weapon magazine) placed on the spawn point, the vehicle spawn is blocked.

Honestly, this is a really poor solution to a problem that didn't really seem to exist. Please revert to the previous approach of allowing multiple vehicles to spawn simultaneously.
