I saw a video on YouTube with some techniques on how to not core your vile. I started doing this and haven’t had problems since.
If I recall correctly, it involves going in at a pretty steep angle, something like 30° off perpendicular to the membrane. Put the attack point of the needle (bevel facing up) right on the existing hole of the membrane and push the needle down slightly to try to reopen that same hole, then slide the needle into it. Once the tip is thru the membrane, you can angle the needle straight in.
