I've got a question about the contracts pack. Is it substituting the default contracts (all of theme) or just add a "new branch/series" of contracts to the standard ones? I just started an heavily modded game (65 mods) with interstellar, tac, near future, far, CTT, etc. and was wondering if it'll remove the contracts I already have or just add some more balanced ones ? I'd like to keep both to have more choices. Thank you in advance
