yesterday i got this item lightning gate mark one out and went into the game and the item is gone , i do not use this item more today went to look at inventory and was not it.

I wanted it to be : '/ item rigged 1x took over because the weight and yesterday was in inventory and today was no more. If I give thanks to check if it is not possible too.

Did you give your account details (username and password) to anyone else? If yes, then he probably fused the item to another item.
