Anyone knows why? Again some ahole went "Oh my god, they're totally not making any money on not so really my intelectual property?" 
This is correct.The main reason, that I remember reading - was that the models used in the mod were taken from another mod from Sins of a Solar Empire. While the mod credited them - the author apparently didn't ask for permission, and the original model creators asked for them to be taken down.
I see. Too bad the moddr didn't ask original designer for a permission, still not a reason to take down the mod. Most modders state "can use if credited" so it might have been an honest mistake. Hope they resolve this.
Actually it is, it can be very painfull to see your work being used without your permission. Plus paradox' mod rules also state you can not use someone elses work unless you have permission. Credditing in case the authors are no longer active can be used a lot however when its an ongoing project you have to ask permission from the author and honor their anwser whatever it is.
@ShadowDragon868 you were telling people that if they wanted a variant of your mod they should make their own, and when someone took you up on that you threw a hissy fit.
Not the same issue.
No, dude. I at no point said "make a variant of my mod." He straight-up ripped off my mod, changed some numbers, and slap-in-the-face slapped it on the workship as "<My Mod's Name>: Balanced" as the title with a logo that clearly aped my mod.
I said to look inside my mod to get an idea how I did it. Not straight-up copy-paste my mod with some changed numbers and an aped logo.
i understand your frustration i really do, but the down side between code and art is that code or script can only be done in so many ways, art is a whole other thing. I can give you 20 different 3d models of a star destroyer and theyll all be unique. but 1+1 in code will still always be 2.
The difference is, your mod was about 5 minutes work. The Mass Effect ship models are months worth.
So is there a Mass Effect ship mod for Stellaris?
