Yes it is glitched. basically around 12-14 mins no matter whats happened you fail. So you have to beat it faster. But since the drop % is same on adv I think I would do adv in about 6-8 mins. My fastest hardmode run was 9 mins.
And I think thats Alexina specific. Like many of the bugs the other servers don't have. If your curious about some of them make an alt on Alexina and try to type normal sentances. Our filter is amazing.
25k exp is filtered for example.
