Future Versions
I began playing TerraFirmaCraft by playing the modpack TerraFirmaGreg-Modern, the desire to deprecate a mod within said modpack brought me to create FirmaCivPlus, to add support for both AFC and Beneath as a result.
This mod was originally an addition to said modpack's "Core" mod, after consideration, i decided to release it publicly
Future versions past 1.20 are not a promise, especially considering that there's a chance that FirmaCiv/Alekiships will become fully Data Driven, letting you add new Watercrafts using Datapacks.
Can I use this in my mod pack?
I literally made FirmaCivPlus to be used in a Modpack called TerraFirmaGreg-Modern, so yes, feel free to use it!
Special Thanks
- Traister101, for helping me out getting started, general guidance and just being insanely helpful
- Alekiponi, for creating FirmaCiv/Alekiships, and Convincing me to release this mod standalone

FirmaCivPlus server crashes on startup – what to do?

Server lagging with FirmaCivPlus – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if FirmaCivPlus consumes the most tick time.
