- Bigger protaractors are already in FOTRSU? YES
- Will remove S-Class mod.
- What about PacificEnvironment 4? Don't add it.
- Is any real (celestial) navigation mod compatible with FOTRSU? NADA
You need to remember there is a huge amount of modifications going into this one mod. For the most part you will not need to add mods to this unless you want to dumb it down and most likely that will end in corruption since no other mod is compatible with it.
Go though your readme files and documentation for Fall of the Rising Sun Ultimate. It is like a Mod to end all mods in how the modders have put in very desirable things so you never have to add to it.
This is also one of the reason there is no final version of it as yet. The modders are smart enough to know there needs to be some game play and feedback to spot bug and unintended overwrites. They have worked very hard on this and from day one have said ... Do Not Add Any Mods to Fall of the Rising Sun Ultimate.
