Did you check the link I gave for the text I gave? you seem to think that you just got it on both for free, you didn’t.
You said you played it on TBC which means if you didn’t pay you only have it active on TBC/Wrath.
You had three options (maybe Four):
- Play the character on Era for free
- Play the character on TBC/Wrath for free
- Pay the £19 (£4 later) and have the character on both Era and TBC/Wrath. (Cloning)
- Do nothing, this meant your character ended up on TBC/Wrath during the Prepatch for Wrath.
number 3 is why I asked you about the link to see if you paid anything. The Clone service (number 3) was never free.
