Hi Cuddii,
If you were playing between 2-5am BST on 20/04 it is possible some items you gained/lost may have been restored to the earlier time. If you gained an item from a CoinFlip the losing player will still have this item in their inventory, so simply ask them to give this item back to you.
If you were not playing during these times then don't worry there is no possibility of losing any items.

Hope that helps!
