Being away for a year, I'm surprised to learn that there has been a clash there !!
I'm not sure to well understand the reasons of this, but...
Please, please... Do not bother SupSuper !!!
You can challenge him, lots of community members are making lots of amazing evolutions, and I'm very grateful for that. But do never forget SupSuper (and Warboy) realized what nobody never did before and certainly will never perform in the future regarding UFO. Even if you sometimes disagree with his point of you, be eternally grateful to him (them) for the amazing job they realized.
I agree with CryptoCactus conclusion (except for suggestion, as I don't really have any opinion on that)
I've been around ye olden internettes a long time, and here's the #1 problem open-source/freeware/fan-made projects run into: dev burnout.
So honestly, Warboy, SupSuper, all yall - fuck trying to please everyone. You do exactly what is easiest - and most fun - for you. If that means making nightlies less accessible, slowing down progress, backtracking, whatever - you do what you need to do. People will bitch and moan no matter what you do. That's just how humans work. So do what you think is best. If anyone disagrees too strongly with you, they can make their own fork or whatever else - otherwise they can dealwithit.jpg
Also, bear in mind, you guys could quit right NOW, and we already have a better Xcom than we've ever had before. You've done it - you've won. The project wasn't abandoned at v0.037 (or whatever) like so many other unpaid projects littering the tubes. We have a complete, playable, new-and-improved game, and we have y'all to thank for that.
If I were you, I would just seal off OXC at either 1.0 or whichever nightly you're most comfortable with, and rename all the new nightlies OpenTFTD - essentially making it its own project. That way you don't have to worry about TFTD support interfering with OXC gameplay, and anyone playing the latest builds would be doing so essentially as beta-testers for project#2, OTFTD. If that makes sense.
Either way, you do what you want/need to do, end-users can suck it up.
Edit: yes, I am a SupSuper inconditional !
