So, I was on this server a while ago and I had a rank and I don't know how to get it back, can anyone help me? I either had MVP or MVP+, I still have my rank on the parkour section of this server but not one islands and I'm not sure why.
The different game-modes on Manacube reset occasionally, and when they do you end up losing everything (rank included). If you want to reclaim your rank on all game-modes, go here: https://store.manacube.com/category/1059611 . The website should tell you whether or not you can reclaim the rank, just filter through the reclaim ranks until you find the one you had.
If you can't reclaim, or don't get your rank back after about 15 to 20 minutes, open a support ticket here: https://manacube.com/support/ and explain the situation
