I tried trading my tokens for materials at Brinks (The token exchanger) in the Haven Bazaar and he wouldn't let me exchange any tokens for any less than ten materials each.
So if I went to exchange Primal Spark tokens for a Warp Dust (that's 10 tokens to 1 Warp Dust), It told me I had to exchange for ten Warp Dusts. So I could only exchange 100 Primal Spark tokens for 10 Warp Dusts.
Tried the same thing at Moorcraft Manor, same result.
Is this a new update for the exchange or did I press something and just didn't notice, or is this a bug?
Tried it again and it's working fine.
