And if you're gonna do a MOD,.. do it properly,.. or dont do it at all

This statement really vexed me. Thank you for that advice. And what have you done for any of these people here that is "perfect"? You are complaining about nav lights. You are making it out to be this huge deal that is a life or death struggle and blaming modders that put a lot of time and effort into making mods for you to enjoy. Like said before, most people who have this bug didn't notice because this is a WW2 combat sim and most don't fly with nav lights on. If you want to make a big deal about it, go fly FSX or install some nav lights the wrong way on the glider you fly and complain about that. Go to UP's site and report this "bug" and maybe someone can help you. I assure you they will if you conduct yourself in a more humble manner and with some tact. Otherwise I'd say, like others here, that there is definitely a mod conflict. Disable any mods besides what is in the mod pack you are using.

As for me and this "stop the world" issue, I run UP2.0 and the lights are perfectly fine. And no I am not color blind.
