What you were expecting to happen, and what actually happened?
Nothing wrong is happening, I guess, only that my invite code is ENEVER_UVLQ_DEACTIVATED, which is kind of strange. It is there for quite some time, I did not want to bother you, if it did nothing, but… I feel a little bit nervous about it, so…
What are the steps to make it happen again?
For other people to make it happen, have their character on two devices, and then, on one of those devices, login with different character - a chracter of a friend or something. As you replace the character, the game thinks that the character is no longer used so it is “deactivated”. This “deactivated” thingy probably does nto do much, though.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
