Fixed a bug where the Prethoryn Scourge couldn't trigger after the Unbidden appeared.
Reported by LeaderEnemyBoss.

Updated for 1.9

Added new restriction so the AI Crisis won't happen at the same time as Swarm or Extradimensionals.
It can still happen before or after them and the other two can still happen at the same time.

Updated for 1.8.2 (forgot something)

- 200 years must pass in-game before a Crisis can occur, up from 150

Updated for 1.8.2

Prethoryn Scourge (Swarm)
- delayed trigger

Contingency (AI)
- rebalanced weigths of the accelerator events

Fixed a bug where multiple instances of the same crises happened.
Thanks to Sarno for reporting the bug and helping with the code.

Simplified the mod, but still not compatible.

Updated for Patch 1.8, aka "Capek".

They reworked the trigger system for crises with the clear intention to disallow multiple crisis, I had to add some parts of the old system to make it happen again and the updated version will not be fuilly compatible because I have to overwrite the new file "crisis_trigger_events.txt".

Renamed

• compatible with other crisis mods
  
• works retroactively on savegames
  
• compatible with ALL known Stellaris patches
