Never had so many problems with CSG

I dont even know, before the last CSG updates i was able to make basically everything.

Now, everytime i try doing something, i get some error or glitch.
Even being 100% accurate, paying attention to having everything perfectly alligned i’m getting errors.
Im trying to make this new gas tank for the bike i’m making, and i’m having so many problems.

That’s it, for now i can just stay still and wait for a fix or something like that.
