I hope you understand that you have deprived players of one of the functions of the Premium Account?
Considering this
1) Is beta, so bugs happen and this server has the only purpose of finding these bugs
2) you get 14 days of free premium monthly to compensate for this kind of bugs
3) the price of premium on beta is reduced a thousandfold compared to regular worlds, because this can happen
I can assume it is fine that this happens
Thanks for reporting the issue.
