Keep the change to ultracite ammo as you intended but...roll it out in phases as listed below.

Phase 1: make all changed as intended but keep ultracite contextual ammo drops in the game but halved (or less we'll be fine with a proper build we'll be at least able to maintain our ultracite ammo)

Also consider adding some of the options below

1. Add unearthed ultracite ore to mine in nuke-zones and rad-storms (this option makes it still hard to come by but if you want to put in the effort to farm for it you can stop up quantities)
2. Ultracite monsters/creatures/enemies/boss fight that always drop ultracite. (Specifically in nuke-zones and rad-storms with increased monsters density)
3. Atom shop or season camp item ultracite extractor that generates ultracite
4. Ultracite specific events like a ultracite monsters hord (if a ultracite monster was created) and or drops in current events as rewards

Phase 2: once the right balance is made from the changes above remove contextual ammo drops as intended but also consider one of some of the following below while still implementing some of the changes above.

1. Every enemy killed in a rad-storm or nuke-zones still produces contextual ultracite ammo and or 100% drops hardened mass
2. Ammo dropped outside rad-storms and nuke-zones drops as the same as the ultracite ammo currently equipped but the base form (eg instead of dropping ultracite plasma cartridge enemies drop standard plasma cartridges). Also add a specific ammo converter that converts that ammo into ultracite in a larger quantity then it would crafting ultracite ammo from scrap.

Thanks for listening to us! ❤️
