I've been testing the new lighting options, brought by Yankes with his great update. I've reduced the light produced by pirates from 15 to 5 (maximum setting which still counts as being in darkness).
This has twofold impact, which I consider favorable:
- You need actual sources of light, like torches, to lit up the night now;
- In that light-level-5 state, the pirates and their surrounings are somewhat visible now - while staying hidden from day vision.
