Yes they are a different company. We actually posted a comment about those flavors a week or so ago addressing that subject. It was just a simple issue of reformulation. Here it is again copy and pasted,
"I have great news!
Currently we're about to add Strawberry Biscuit, Kigola, Kilanca and the other flavors back to the site. They will be listed under "Nicotine River". Here is the link: https://www.nicotineriver.com/collections/nicotine-river-flavors
Do not worry about the company name change. These are the exact same flavors you were purchasing before. After constant efforts of reformulation and no definite results we were lead to the conclusion that it would be best to have these flavors placed under the Nicotine River name once again.
Please note that these flavors: Cream Dream, Golden Eye, Heaven, Kigola, Kilanca, Ocean Myst, Paradiso, Strawberry Biscuit, Vanilla Bacco are the ONLY flavors being impacted by this name change. This will not be happening in the future to any other flavor.
Feel free to ask questions here and I will respond promptly! Thank you!"
