It seems like this is one of those lessons in life a large portion of guys have to 'learn the hard way'. I sure did. I was being too shy. Then, of course, I went the other way, cooked a gram of other wise nice oil and destroyed a cart in the process. And not to worry about there being 'so much to learn', as you go along that happens. It's how adults learn. Kids learn by rote, they repeat multiplication tables until they become habit. Adults build complex skill and understanding sets one step at a time, entirely different. If you want to teach something you need to get past that.
Anyway, enough cosmic stuff for a while. If you can see an uneven surface it's clear stuff didn't flow in and settle well. However, it's now cold so it's going to be much harder to melt it down without overheating. The key is understanding the risks I think. The seals we're most concerned about are at the bottom at about the 1/3 level up. This area has to stay cool enough to hold onto or we'll trash the seals. But it also has to end up hot enough to melt the oil. So here goes:
Hold it at the 1/3 point and keep rolling it. Stay conscious of the heat you feel, you want it warm but not real hot through the process. Start heating at about the mid point. Stainless conducts heat poorly and the walls are thin, so the heat doesn't 'flow down' easily when there's no oil inside. When it's warm under your fingers, move up. Keep the heat on, keep it rolling and keep feeling the heat at your finger level. If your lower part cools, quickly lower to the middle of the cart and give it a second or two blast of heat before returning back up. Keep it warm below as you move up. You want the first melted oil to flow all the way down past the air bubble, if it stops again lower down the hill gets steeper. If you're lucky you can feel a quick but modest rise in the temperature under your fingers as the hot oil drops down, but don't key on this it might not happen.
Then prime carefully and test again. I've done this two or three times without any problems since I learned the lesson about enough but not too much heat.
Best wishes. It's worth getting a handle on, IMO.

Ah, I don't mind losing the gram; it was only ten dollars.
I'm actually a bit suspicious about the quality of the oil (if it even is oil). Is it supposed to taste sweet? I have a feeling it might be some tincture, rebottled, and made to look like hash oil. I've never used hash oil prior to this, but for $10, I'm having doubts! But why would my favorite collective lie? Aren't people supposed to be honest?! :'(
I did go ahead and try to fix it myself with a hot needle and lighter, but it still didn't work, so I gave up.
But I'll try again right now using your method.
And thanks for the help; it is extremely detailed and very helpful.
I got my cartridge out of my bag, and it's profusely leaking. Well, not that much, but it's leaking enough to just forget about it. I put some saran wrap on the bottom since I suspected it would keep leaking. It's pretty gross looking haha. I'm just going to toss it, fuck that.
I WILL keep in mind how to properly fill a cartridge though, for next time, so thank you very much again.
Actually, I won't toss it. I'll just reclaim the oil or something and dissect the cart. Should be fun.
Oh and dude, would you mind telling me how long the Omicron V1 battery is supposed to last? I never discharge the battery completely, and I charge it every day. I've read on a few sites that that helps prolong battery life, but I just do it out of habit...
