Added a config option to allow re-enabling tier 3 enemy groups
1.0.3
Allowed using vanilla spawn amounts by setting the spawn count of a tier to -1
1.0.2
When "Prioritize closest points" is disabled it no longer overrides the vanilla logic for choosing the spawn location (since vanilla now excludes level points in the truck)
1.0.1
Fixed a small oversight with the enemy spawning collision check
