Fix for OFFENDER mission not spawning cave worms and preventing completion

We've released a number of hotfixes this weekend to address important issues and get improvements into players' hands as quickly as possible, rather than waiting for the next scheduled update.
Thanks for your patience and continued support while we continue working to improve the game.

- Fix for OFFENDER not spawning cave worms as intended
- Preventing Double Calling of Prebuilt Complete following the older flow
- Preventing Double Spawning of Loot in some prebuilts
