Try doing one of these things.
Sometimes it takes a few tries to combine.
• Have 1 needed essence sent to you by gift to complete the combo.
• Trading 1 group of the needed essences to one acc and back.
-You can also send 1 group of essence through gifts if needed.
• Trade all of the needed essences to an empty (just one w/o essences) acc.
If you are having trouble with the model rocket item, please read the Troubleshooting Solutions here before going to the spoiler below.

To everyone who found the combinations when they became available & sharing info.
The model rocket is NOT incorrect. As I have stated in previous posts on this thread, math is not incorrect.
Please make sure you are troubleshooting correctly, if you have any questions feel free to wall me, @Ayrshi, about it.
If that is not enough to convince you here's my proof.
If you have proof of another combo set for ANY combo please show me and I will test and correct accordingly.
After a long while, over a year, of trying to contact OP about edits and updates, I decided it was time for an update to this thread so it could be more useful to the community. I teamed up with Ayrshi who has been working hard to keep this thread up to date in the comments to make a new thread you can find here.
