This is probably not a bug but im pretty sure it wasnt intended too. Well i read in a thread that you can vote 12 times in the spanish servers and that the votes are shared so i rushed to make a colony and start voting. To my surprise i got 50 more tokens and i was like lolwut? i checked my events and found that i have been awarded the top 100 player achievement. Thats pretty stupid because there are only 59 players on the server and technically everyone is a top 100 player. Although i welcome the tokens because i really need a boost atm i am a bit disappointed that i didn't earn that achiev.

The spanish servers are just starting up, so it's to be expected for a while. Just accept the achievement as it is, and take it as memento of being one of the first on the server.
