I have the NovaPunch pack though, and I have those parts, but it doesn\'t recognize them for some reason. I think its because the new folder names are like NP_YMA-whatever. Instead of just YMA-whatever. It\'s being a total pain in the arse at the moment.

Hmm, what mods are you running? Apparently I am missing that command module and the YMASas modules. No idea what pack those are from.

It sounds like you may have an issue with one of your fuel lines. Double check your fuel lines and their directional arrows. I had a similar issue in one of my launch stages once. A backwards fuel line was causing one of my internal radial stages to empty too fast, and when the external stage decoupled the next internal tanks were already drained causing an engine to shutdown and the entire ship to tilt to one side as if a drunken Kerbal was piloting it. What I usually do is I connect my external tanks to the internal one, even if there are multiple radial stages. That way the external tanks get used to fuel both the external and internal engines, so that the external tanks drain quickly and can be decoupled while leaving the internal tanks full of fuel.

Either post a picture of the vessel or maybe even upload the .craft file so we can see exactly what the deal is. It could be a number of different reasons.

I\'m having a hard time seeing where the vertical decouplers are for the outer tank separation, are you using addon parts for decouplers? Check their ejection strength. Try using radial couplers instead, they tend to push the empty stage away instead of just pushing it straight down. Mechjeb tends to start turning early at 10-12km, I assume your launch stage is still burning at that point so when it releases its hitting you from the side as its trying to drop straight down. Stack multiple radial decouplers on each other if you have to.

Aww man , I was having the same problem and hoping it was just me, as opposed to the actual part being borked now with the new update. It can\'t be that difficult of a fix, because the base and clutches work ok. Anyone know how to fix this issue? Thanks!
