I wanted to add an extra bounty to a question I had already bountied (at 100 rep) to make its reward comparable to a very similar question I had also bountied. I wanted to add another 150, but the minimum allowed is now 200.
Out of curiosity I tried to add a bounty to the other question that I had already bountied at 250, and its minimum was 500.
Is this an intentional change or was it always like this? Is this a bug?
